中文摘要： 县级行政单元是我国生物多样性保护地的管理主体和保护资源的配置受体，识别具有互补性的县域保护优先区可为区域保护地网络优化和保护资源优先配置提供直接依据。云南生物多样性保护极为重要，但近期研究表明，已建云南保护地仅能保护云南生物多样性极为有限的部分，存在明显的空缺，识别具有互补性的保护优先区、优化已有保护地网络成为云南生物多样性保护的当务之急。本研究将系统收集已调查记录的云南国家重点保护动植物物种的分布信息，构建县域单元的国家重点保护动植物物种的空间分布数据库，分析国家重点保护动植物物种在云南县域单元的分布格局；应用保护生物学理论和方法筛选具有互补性的云南县域保护优先区，并对其合理性开展多模式判识，进而确定适宜的云南县域保护优先区。分析已建保护地、新规划的保护优先二级区、适宜的县域保护优先区的保护现状和空缺；在此基础上，应用系统保护规划理论，提出云南保护地网络优化相关策略。

英文摘要： In China, county-level governments are the major management bodies of the Protected Areas (PAs) and the basic receivers of conservation resources. The identification of complementary county priority areas with analyses of their conservation gaps can provide direct basis to optimize regional PAs (usually established based on natural biogeographic units) network and prioritize the allocation of the limited conservation resources. Yunnan province, southwest China, is one of the most diverse and unique biodiversity regions on earth. The conservation of Yunnan biodiversity is very important for regional, national and global eco-security. Presently, the established Yunnan PAs, including all nature reserves and other kinds, had nearly covered 10% of the provincial total area. But some recent studies clearly revealed the established Yunnan PAs only represents the limited part of Yunnan's biodiversity. It's very urgent to optimize present Yunnan PAs through identifying the complementary priority areas. Through systematical collection of the recorded distribution data of National Protected Wild Species (NPWS) in each county (county-level city or city-governed district) of Yunnan, this study will first construct the county distribution database of NPWS and examine the county distribution characteristics of NPWS in Yunnan. Methods of conservation biology will be used to identify the complementary county priority areas in Yunnan. The maps of Global 200 ecoregions and Hotspots regions (global scale), China key (or priority) regions for terrestrial botanical diversity and biodiversity conservation (national scale), and Yunnan newly planned priority regions for biodiversity conservation (provincial scale) will be used to examine the spatial linkage of the identified complementary county priority areas at these three scales. The study will also explore the representativeness of the identified complementary county priority areas for the typical Yunnan's biogeographical units, which are determined by using the Yunnan Vegetation Map and Landform Map. Furthermore, human-used land area coverage, population density and GDP per capita will be used to analyze the human disturbance intensity of the identified complementary county priority areas. Based on the analyses of spatial linkage, representativeness and human disturbance intensity, the study will sort out suitable county priority areas. Then, the study will examine the conservation gaps of the established Yunnan PAs and Yunnan newly planned priority regions for biodiversity conservation with the identified suitable county priority areas, and the gaps of the identified suitable county priority areas with the established Yunnan PAs. Based on above-mentioned studies, theory of systematic conservation planning will be applied to improve the present Yunnan PAs system and propose the optimization strategy.
