Conservation Value Evaluation And Reasonable Distribution Of National Nature Reserve For Forest

Natuer reserves for forest is the main body of nature reserves construction in China. Company with the conversion from large-scale rescuing construction to scientific intensive model of the nature reserves, serials of problems have been considered by the production and management administration, for example, the rationality of the distributions of existing national forestry nature reserves, the protection gaps, how to quantify the evaluation of the reserves values and how to promote the reserves scientificly, the finished nature reserves need to be invested and built preferentially and so on. Based on the evaluation of conservation value and the gaps analysis of the forest nature reserves, the objective of this paper is to approach and analysis the quantitative evaluation method for the conservation value, scientific promotion, and gaps analysis of the forest nature reserves. It will provide important theoretical and technical supports for the management administration's rational distribution, scientific planning, and key management of national forest nature reserves.The main conclusions of this research were as follows:(1) Constructed a quantitative assessment indexes system for forestry nature reserves consisted of 4 levels including 29 indexes using hierarchical analysis and expert consultation methods, determined the weights of all levels and the comprehensive weights of each index.(2) Divided our country into 3 natural conservation geographical regions,7 natural protecting geographical areas,33 natural protecting geographical areas,311 natural reserve geographical units by selecting highly trusted natural geographical regionalization programs, considering the integrity of non-zonal features such as topography and surface composition of the material and the special features of chinese forestry nature reserves construction, processing the integrated geographical division of nature reserves by GIS technology consulted other types of special zoning schemes.(3) By applying "fast clustering" and "Gold segmentation optimum choice" methodology, setting the natural conservation geographic zone as the zonal evaluation unit, the grade interval and grade standards of the evaluation indexes of conservation value of forestry nature reserves was established, the protection value of forestry nature reserves in all geographic areas quantitatively was assessed,2 gear grade interval and 15 grade standards of natural conservation geographic zone evaluation indexes,374 conservation value index series of forestry nature reserve were obtained. The national standard indexes of the conservation value of forestry nature reserves in every natural conservation geographic zone were also calculated.(4) The analysis of the protection gaps of national key protected forestry wild animals, wild plants, natural geographical distributions showed that, there existed deficiency of national forestry nature reserves in 189 nature reserves geographical units,146 natural conservation geographical units in the main forestry distribution area. There were 37 forest vegetation formation(for example Quercus baronii forest, Cyclobalanopsis myrsinaefolia, Carpinus fargesii. forest, Cyclobalanopsis glauca, Paliurus hemsleyanus Rehd. forest etc), 56 national key protection forest species(for example Archangiopteris bipinnata, Cephalotaxus lanceolata, Cupressus gigantea, Abies yuanbaoshanensis, Calycopteris floribunda, Primulina tabacum etc) and 16 national key protection forest animal species(for example Presbytis poliocephalus, Lagopus mutus, Anorrhinus tickelli, Aceros undulatus, etc) haven't been protected in the existing national forest types nature reserve system.(5) According to the results of the current construction and gap analysis of national forestry nature reserves, combined with the results of evaluation protection value,107 provincial forestry nature reserves should be upgraded, combined, expanded,12 new national nature reserves quarter should be built, in order to achieve the goal of rational distribution of national forest type nature reserves.(6) Introduced the conception of the "national nature conservation spot" according to the "conservation spot" and "national nature reserve", proposed some constructive opinions for its building and administration.(7) According to the principle of national forestry nature reserves construction priorities, combined with the results of protection value evaluation and gap analysis,166 forest nature reserves should be constructed preferentially.
