Abstract
The invention discloses a testing method for bird species conservation priority, which can solve the problems of bird species protection status and priority, realize the sequencing of the bird species conservation priority, provide specific protection priority indexes, and thus enhance the availability and comparability of bird species in conservation value assessment of natural reserves. Birds are common indicators and indicator species in the conservation value assessment of the natural reserves, but the protection priority status and sequence are still not represented effectively, directly and quantitatively and thus cannot be applied in the conservation value assessment of the natural reserves. Therefore, the protection priority status of various bird species can be quantified in the form of indicators so as to be effectively applied in the conservation value assessment of the natural reserves.
Description
Technical field
The present invention relates to the nature conservation field, is a kind of method of testing of birds species priority protection grade, is applied in the bird preservation value assessment of wilderness area, for conservation value assessment in wilderness area provides available instrument.
Background technology
Birds are important indicator species of current nature conservation, the conservation value that is widely used in the wilderness area as important index with manage and protect in the assessment of effect.
The protection status of birds is admitted the assessment result that the IUCN of World Conservation Union proposes usually at present; China is domestic usually also with reference to " wild animals of national priority protection register ".
But these results are generally descriptive, more wide in range grade classification.Though can show certain general character from people's protection consciousness and willingness to pay, can not in quantitative evaluation, use neatly, also restricted its value.Particularly, when the birds species have compromised grade simultaneously, when laying special stress on protecting multiple attribute such as rank and peculiar classification, the priority protection status of the different birds of comparison of also having no idea at present.
Therefore can need the eager problem that solves for conservation value assessment in wilderness area provides quantifiable birds species priority protection degree methods means to become.
Summary of the invention
In order to solve the quantification problem of birds species priority protection degree in the conservation value assessment of wilderness area; The invention provides a kind of method of testing of birds species priority protection grade; It can solve birds species conservation status and priority problem; Can realize the ordering of birds species priority protection, provide concrete priority protection index, thereby strengthen utilizability and the comparability of birds species in the assessment of wilderness area conservation value.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of method of testing of birds species priority protection grade, said method comprises the following steps:
(1) step 1: utmost point danger CR, the EN in imminent danger that confirms to delimit in the red register of the IUCN of World Conservation Union species, is prone to danger VU, near endanger NT and do not have the birds species that China of 5 grades of danger LC distributes; Confirm that listing national I level, II level in " the wild animals of national priority protection protection catalogue " of promulgation in 1989 lays special stress on protecting the birds species; The provincial focused protection bird kind that clear and definite each province announces.According to " Chinese species red register " and " birds in China classification and distribution register ", confirm its distribution character in China, being divided into Chinese peculiar distribution, China is four types of frontier area distributions for main distributive province, China for less important distributive province and China.
(2) step 2: obtain the birds species information according to step 1, the birds species are carried out assignment according to different attribute, adopt geometric series method, even a back ratio number with last is a constant, set the highest assignment 8, constant gets 2, and ordered series of numbers is (8,4,2,1); Concrete assignment is following:
1. the birds of the different compromised grades of the red register of the IUCN of World Conservation Union species: utmost point danger grade CR birds, 8; Grade EN birds in imminent danger, 4; Be prone to danger grade VU birds, 2; Nearly danger NT grade and nothing danger LC grade: 1.
2. different birds of laying special stress on protecting grade: national I level is laid special stress on protecting birds, 8; The II of country level is laid special stress on protecting birds, 4; Provincial focused protection birds, 2; The birds of non-focused protection, 1.
The birds of the peculiar degree of 3. different geographic distributions: Chinese peculiar distribution, 8; China is main distributive province, 4; China is less important distributive province, 2; China is the frontier area, 1.From step 3: can set up birds species priority protection formula of index according to step 1,2:
B
i＝T
ti·N
ni·E
ei
B
iBe birds species i priority protection index.
T
TiFor birds species i in the red register t of the IUCN of World Conservation Union species grade; Be utmost point danger grade, grade in imminent danger, be prone to danger grade, near endanger grade and do not have the assignment of danger grade; Be 8,4,2 or 1, corresponding successively utmost point danger grade CR, grade EN in imminent danger, the grade VU that is prone to endanger, " closely endanger NT and nothing danger LC grade ".
N
NiFor the assignment that birds species i lays special stress on protecting for the n level, be 8,4,2 or 1, corresponding successively national I level focused protection, the focused protection of national II level, provincial focused protection, non-focused protection.
E
EiFor birds species i is the peculiar birds of e class; Be that Chinese peculiar distribution, China are that less important distributive province and China are the assignment of frontier area for main distributive province, China; Be 8,4,2 or 1, corresponding successively Chinese peculiar distribution, China are that main distributive province, China are that less important distributive province and China are the frontier area.
The meaning of priority protection index is to take all factors into consideration its priority protection status from the compromised degree of birds, focused protection rank and the peculiar degree of geographic distribution three aspects; And lay special stress on protecting the indication of object as the wilderness area, also can weigh wilderness area conservation value size and the preferential status of building.
The Bi span is [1; 512]; Numerical value shows that more greatly the compromised degree of birds species is high more, the focused protection rank is high more, the peculiar degree of geographic distribution is high more; Explain that the endangered risk of species is high, the protection attention rate is high, habitat importance is high, conservation value is high more, and human society should give priority protection; Otherwise the species conservation status is low more.
Birds species i is meant certain birds.
Birds are index and indicator species commonly used in the conservation value assessment of wilderness area.But quantization means effectively directly perceived is failed in its priority protection status and ordering always.So the present invention carries out index with every kind of birds species and quantizes, and can effectively utilize the conservation value evaluation work in the wilderness area.
Embodiment
In crested ibis, for example, the present invention provides a first level of protection of bird species tested, said method comprising the following steps:
(1) Step 1: Determine the crested ibis in the World Conservation Union IUCN Red List species designated as endangered by the threat level grade (EN); determine the crested ibis in the "national key protected wild animals" and included in the national key protection class I ; determine ibis bird species endemic to China.
(2) Step 2: According to the information obtained from Step 1, depending on the crested ibis threatened levels, different protection levels and geographical distribution characteristic three aspects of property valuation, endangered, etc.? Class (EN) Assignment 4, the national key protection class I Assignment 8 Assignment 8 unique to China.
(3) step 3: according to step 1,2, by birds species priority protection formula of index: B
i=T
TiN
NiE
EiCalculate;
Specifically: B
ibis = 4 × 8 × 8 = 256.
In this case the priority ibis bird protection index higher, indicating Crested Ibis in bird conservation has priority.The world's endangered crested ibis, I national key protected and only in China, the presence of wild populations, so the index can fully reflect the priorities of Crested Ibis Conservation Value and status.
The meaning of priority protection index is to take all factors into consideration its priority protection status from the compromised degree of birds, focused protection rank and the peculiar degree of geographic distribution three aspects; And lay special stress on protecting the indication of object as the wilderness area, also can weigh wilderness area conservation value size and the preferential status of building.
The Bi span is [1; 512]; Numerical value shows that more greatly the compromised degree of birds species is high more, the focused protection rank is high more, the peculiar degree of geographic distribution is high more; Explain that the endangered risk of species is high, the protection attention rate is high, habitat importance is high, conservation value is high more, and human society should give priority protection; Otherwise the species conservation status is low more.
Birds are index and indicator species commonly used in the conservation value assessment of wilderness area.But quantization means effectively directly perceived is failed in its priority protection status and ordering always, thereby can't in the assessment of wilderness area conservation value, be applied.So the present invention carries out index with every kind of birds species and quantizes, and can effectively be used in wilderness area conservation value evaluation work.
What should explain at last is: obviously, the foregoing description only be for clearly the present invention is described and is done for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, can also make other multi-form variation or change on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among protection scope of the present invention.
