| Abstract | 怎样合理有效的以最小的代价对生物多样性进行保护空缺分析及网络布局优化，这是新疆生物多样性保护研究的空白。本研究以生态环境部划定的新疆天山-准噶尔盆地西南部生物多样性优先区为例，统计该研究区域2642种维管束植物，609种脊椎动物，和6类一级生态系统，21类二级生态系统及其群系，并统计该区域保护现状，将该区域划分为以保护区域、未保护区域和人类活动区域三种类型，基于系统保护方法，采用C-Plan规划软件在未保护区域开展保护网络空缺研究分析，根据物种的珍稀、濒危及特有等特点进行赋值排序，筛选出7种重点保护的维管束植物，13种重点保护脊椎动物，以及该区域重要生态系统，结合土壤、水文、气候等因素，计算其保护目标范围，及该区域的不可替代性指数，根据不可替代性指数确定具有高保护价值的区域，分析这些区域与现有保护地的关系，并进行保护网络的优化。主要结果如下：（1）基于系统保护规划方法，根据筛选出的物种信息，结合其自身分布范围等信息，利用C-Plan规划软件进行不可替代性指数数值，其结果为：不可替代性值大于等于0.4的面积为4750km²，占区域面积的3.134%；0.2至0.4的面积为111575km²，占区域面积的73.625%；小于0.2的面积为35219.76km²，占区域面积的23.240%。（2）根据不可替代性指数确定研究区域内的“重要”区域主要分布在天山中部山区、天山西部山区、准噶尔盆地西部及巴音布鲁克自然保护区东侧。（3）结合以上结论进行空缺分析并进行网络优化布局，研究区域共有8种形式保护地，面积相对较大，结构较为分散，保护网络不明确。研究范围内具有高保护价值的重要区域主要分布在天山中部及西部山区地带，这一地区的自然生态环境类型丰富，是众多珍稀、濒危及特有动植物的栖息地，同时其生态系统层次丰富，是调节该区域乃至整个天山山脉生态平衡的重要部分。具有较高和一般保护价值的区域分布在优先区内各县市平原地区，这些区域保护价值一般，但多集中于人类活动区附近，在今后开发利用时需要谨慎。并建议在新疆-准噶尔盆地西南部优先区新建保护区1处，升级已有保护区3处；新建保护小区3处。 |
| Other Abstract | How to reasonably and effectively carry out biodiversity conservation planningat the minimum cost is the blank of biodiversity conservation research in Xinjiang.Taking Tianshan Mountains in Xinjiang and southwestern part of Junggar Basin as anexample, according to statistics, there are 2642 species of vascular plants, 609 kindsof vertebrates, 6 types of primary ecosystems, 21 types of secondary ecologicalsystems and formations in study area. On the basis of protected situation, the studyarea is divided into three types: protected area, human activity area and unprotectedarea. Based on the system protection method, using C - PLAN planning software tocarry out the protection network analysis in the unprotected area. In line accordancewith rare, endangered, unique and other characteristics of species, assign values tothese attributes and sort by score, 7 kinds of vascular plants and 13 kinds ofvertebrates were selected. With soil, hydrology, climate and other factors, getting therange of species, the protection target range and irreplaceability index of the region.Above data, especially the irreplaceability index, it is used to determine the areas withthe highest protection value, analyze the relationship between these regions and theprotected areas, then optimize the protection network. The main results are asfollows：(1) Based on the system protection planning method, combined with the selectedspecies information, their own distribution range and other information. C-Planplanning software is used for the value of irreplaceable index, and the results are asfollows: The area of irreplaceable value greater than or equal to 0.4 is 4750km²,accounting for 3.134% ; the area of 0.2 to 0.4 is 111575km², accounting for 73.625% ;the area smaller than 0.2 is 35219.76km², accounting for 23.240%.(2) According to the irreplaceability index, the “most important” areas in thestudy are mainly distributed in the mountainous of the central Tianshan Mountains,the western mountainous areas of the Tianshan Mountains, the western Junggar Basinand the eastern side of the Bayinbuluke Nature Reserve.(3) The result shows that there are 8 types of protected lands in the study area,with characters of relatively large proportion, scattered structure and unclearprotection network. Areas with the highest protection value are mainly distributed inthe central and west Tianshan Mountains, which is rich in natural environment typewith the habitat of many rare and endangered and endemic plants and animals. Thisarea with the highest protection value plays an important role in the ecologicalregulation of the entire study area even to the whole Tianshan Mountains. The regionwith general protection values is mainly distributed in the plain areas of counties andcities. They are not the most urgent place to protect, but are mostly concentrated in thevicinity of human activity areas, so these areas need to be carefully developed andutilized in the future. It is suggested to build one new reserve in the study area, 3newly built protection zones. |
