Report of Yinchuan of Li Genghu of reporter of Chinese environment newspaper cheats pleasant of short for Shaanxi Province the first times to border banquet of couplet of palaver of collaboration of region economy technology can be in Yinchuan city to conclude a few days ago rather. Conference member unit will hold couplet seat every year henceforth one borders banquet of couplet of palaver of collaboration of region economy technology is met, make border region economy circle and zoology are encircled. In August 2004, city of Yinchuan city, stone mouth hill, Wu Zhong city, halfback city, solid former city, city of A Lashan alliance, black sea, E Er is much this the peace such as the city, Yu forest city, Yan’an city, smooth cool city, city that celebrate this world cheats pleasant of short for Shaanxi Province to border the city of 12 ground level of the area with 17 counties, study area development and environmental protection the way to deal with a situation jointly, make pleasant of peaceful unconscious short for Shaanxi Province border region economy, zoology is encircled. Come 6 many years, 29 members city is in all many sided such as traffic, wholesome, education, environmental protection, travel strengthen collaboration and communication ceaselessly.

By the crisis, including the Red Book in said on several, very dangerous, endangered, vulnerable crisis, these things are included to the Red Book. We are more than 30,000 kinds of plants, only 45 have access to thousands of where Redbook, and possibly over, and now is doing the Red Book, is likely to reach 20, which is to be
Protected. 16:15 Xue Tatsumoto: this is too complicated. Sometimes we will simplify, simplify to 56, good operating point. Too complex not very good operation, but the system is this system. 16:10 Xue Tatsumoto: the ninth species is "not assessed" that has never been assessed. 16:10 Xue Tatsumoto: The Eighth is "insufficient data" do not know, do not know for years
The existence of this species does not exist, no one has done before, no data, this negative evaluation, it is called lack of data. 16:10 Xue Tatsumoto: The seventh is without risk, is not dangerous.
 
 16:10 Xue Tatsumoto: The sixth is near threatened. 16:10 Xue Tatsumoto: The fifth is vulnerable, that is very easy to go extinct, it is vulnerable to

Even less, I said only 20 of which are Red Data Book, we not only protect biodiversity is to protect all species, but also protect all of the genes, as well as all ecosystems. Three systems should be protected, not just species, but also cherish the endangered species. 16:16 Moderator: one is called "orange" online friends to Professor Xue was
A question, or to protect rare and endangered species is not rare and endangered species protection is the conservation of biological diversity? 16:16 Xue Tatsumoto: Yet another is to protect the species, after the state law, which is based on Red Book, Red Book by risk factors listed in, not only by the risk factors, it also has economic value,
If the economic value is relatively high, though not endangered, but it can also be protected. Therefore, it is the two concepts, one is the concept of the endangered Red Data Book, a national protected species concept.
 16:15 Xue Tatsumoto: We do Wild China Red Data Book, which is based on biological factors to assess the endangered plants, animals, the degree

The rate of extinction of species on Earth in more than a thousand times the natural extinction rate accelerated. Among these species left in the invisible world, and left the Earth, left the companionship of our human environment. Management from the government concerned, as one of the staff concerned, this is a very heavy sense of the situation, felt indeed
A very important and glorious responsibility. From the perspective of our work, and calls for greater efforts to slow the rate of species extinction. 16:16 Moderator: Before we have collected a set of data, the data is described, the rate of loss of species by the loss of a species generally accelerate to a daily loss of one species per
Hour. Would like to hear two experts on how such an argument is the view?
 16:16 Xue Tatsumoto: say a part of. I have talked about three levels of biological diversity: an ecosystem, one species, one gene. He said the protection of species is a large part of the conservation of biological diversity. Treasure, if only to protect endangered species is

But rather fast, it disappears fast, to illustrate, explain a direction, a trend that the elimination of fast species, but also human impact. Do not care is an hour or two hours.
 16:17 Xue Tatsumoto: from the scientific perspective, this statement, you said it wrong. Disappeared definitely disappeared. I have to tell a secret, you talk about a higher plant, a
Higher animal, you want it to extinction, it is not easy under the conclusion. Now determine how many are not extinct, but why just one species that disappeared for an hour then? Is this way: we are talking about is the big concept of species, 1.5 million kinds, or 5 million kinds of that 30 million kinds. Is that many
Species have not yet identified, has not been recognized, it disappeared. For example, in tropical rain forests, many of the insects, in fact up to now there is no identification, no understanding, no one to do research, to record it. If you cut a piece of woods, the woods disappeared, while at the same time is the disappearance of hundreds

As fire. Some are manmade, some, not man. For example, mine, or mine a dozen, the forest on fire, and burned a large forest, but I want to emphasize that human factors account for much, and now people overlogging, overexploitation, found a medicinal system objects, once we have adopted, while in the adoption of ecosystem destruction, and there are varieties
Of homogeneity and species of rice, we have focused on several varieties of species, many good, good variety, would be lost, and many find can not be found, some of which preserved in the library, which kept things in the library as long in the land which can truly reflect the genetic diversity, it will be weakened by the weakening
Of genetic diversity. In that case, the human factor is accounting for a large proportion. We should protect biodiversity, we must control the manmade sabotage.
 16:19 Moderator: Now in the end what is in the threat to our biodiversity? Professor Xue mentioned earlier is not only human activities inside. 16:17 Xue Tatsumoto: it shows do not care one hour, two hours,

Traditional practices, complete not been formed.
 16:20 Zhu Guangqing: In fact, he asked a very professional advice. We Xue better answer this question. I simply talk about. Biological diversity is a new concept, it and our traditional understanding of the bioecological point of view and meaning of life, has the distinction. The scope of its larger, newer content. Its consideration, evaluation,
Ways and means, not only in the past conventional analysis and evaluation of biological communities, species have a certain relationship between the evaluation, is also somewhat different. 16:20 Moderator: one called "inquisitive" in the User to the Secretary Zhu raised the question, how to measure biodiversity, what with the standard measure of land or grassland to measure forest cover ?
Measure of the proportion of biological or ecological measure used? How to measure the criteria? 16:19 Xue Tatsumoto: mainly human activities. Of course, there is not a human activity. In fact climate change is the human factor. Some natural factors and human activities related to this, there is a natural. Such as earthquakes, floods, these people can not control, such

Diversity, diversity level is low, it is not easy to resist certain pests or disease from occurring. If natural forests, natural forests will be able to resist the outside world some of the pest, its relatively strong resistance.
  16:23 Xue Yuan up: I have to add something. I think probably from a biodiversity assessment of several aspects: First, diversity index.
In a certain area, how many species, the number of ecosystem operation, the number of genes, species diversity, particularly for agriculture, livestock manmade use of this genetic diversity, diversification is higher. 16:23 Zhu Guangqing: We have the traditional biological evaluation, determination of a region, such as a piece of grass species, biological total stock of a region, such as one
Square kilometer of forest ecosystems The composition and content. However, in terms of biological diversity itself, there are many evaluation methods, many scholars in the exploration, international organizations, from the "Convention on Biological Diversity" in terms of doing some research topics are also not yet formed a very authoritative, unified evaluation standard, but in some areas, learn some aspects of

Third rarity. I have here is 100 kinds of, you the 100 species and 100 species of me is not the same, my 100 species are rare, endangered, and are important economic species, are useful, better, on like a forest of 100 hectares and 100 hectares of grassland is not the case, and 100 hectares of flowers and trees are
Not the same, only a few kinds of flowers and trees. This is not the same. There rarity of ecosystems, such as QinghaiTibet Plateau, I was unique in the world did not, as I here, which I have yak, Tibetan antelope, which are unique to the world. 16:23 Xue Tatsumoto: The second is to naturalness. Is the woods, a place
To be this natural, not artificial. Plantation species in that, it is called diversity, yet? It a species. Shajiabang the South, the North is the Legend, the South is the desert, the North is poplar, it is not of biological diversity, it is natural, it is artificial. The woods are the woods is better than no good. But he sent

Come. 16:27 Moderator: Just now you said that the stability of the region, for the entry of alien species, is a good thing for us, or pieces of bad things, can it be said the introduction of a species, our species on the multiout?
 16:26 Xue Tatsumoto: Zhu Secretary just talked to evaluate many criteria. I just said here, part of
The standard, far from enough. Many people study how to evaluate the diversity of an ecosystem, there is rapid assessment, this species can be seen in a glance, there are several indicators, what to see, rich not rich. There is a data analysis method, the practices of some plots to be calculated.
  16:26 Xue Tatsumoto: 4 is stability. It is
Not easy to destroy, if the system, this species can easily be destroyed by climate change a little bit about it right away to die, or to a flood, in natural conditions, it is easy once it weaker, that is, said weakening and stability. If the system is stable, I think biodiversity is higher than the weaker. 16:26 Xue Tatsumoto:
