【摘要】：自然保护区是国家用法律形式确定的为长期保护和恢复自然综合体和自然资源整体而划定的一定空间范围,其根本目的是为了保护重要的生态系统及其环境,拯救濒临灭绝的物种群落,或者是为了保护自然历史遗产。对自然保护区的生态敏感性分析是进行保护规划的重要依据。论文以南雄市观音岽自然保护区为研究对象,采用实地调查和GIS分析方法,对观音岽自然保护区进行生态敏感性分析,主要研究成果如下:(1)总结了自然保护区生态敏感性评价的理论和方法,归纳了自然保护区生态敏感性评价指标体系,并根据观音岽自然保护区实际情况建立了 5个准则层9个评价因子的生态敏感性评价指标体系。(2)实地调查了观音岽自然保护区资源现状。发现保护区内共有维管植物169科,498属,857种。其中蕨类植物共有23科32属49种,种子植物共有146科466属808种,其中国家一级重点保护野生植物2种,二级保护植物9种。保护区共有脊椎动物33目89科234种,其中国家二级重点保护动物11种。并进行了保护动植物资源的分布和生境状况调查。(3)观音岽自然保护区生态敏感性评价。首先,在保护动植物生境状况分析的基础上,建立了保护动植物生境敏感性评价指标体系,对保护动植物进行了生境敏感性评价;其次,在单因子评价的基础上进行了自然保护区生态敏感性总体评价。(4)根据评价结果,对保护区进行了生态功能区划,并提出了相应建议。
[Abstract]:Nature reserves are defined by the state as a legal form for the long-term protection and restoration of natural complexes and natural resources as a whole defined a certain range of space, its fundamental purpose is to protect important ecosystems and their environment. Saving endangered species communities. Or in order to protect the natural and historical heritage. The ecological sensitivity analysis of the nature reserve is an important basis for conservation planning. This paper takes Guanyin Dong Nature Reserve of Nanxiong City as the research object. Field investigation and GIS analysis were used to analyze the ecological sensitivity of Guanyindong Nature Reserve. The main research results are as follows: 1) the theory and method of ecological sensitivity evaluation are summarized. The ecological sensitivity evaluation index system of nature reserve was summarized. According to the actual situation of Guanyindong Nature Reserve, the ecological sensitivity evaluation index system of 9 evaluation factors in 5 criteria layers was established. The present situation of resources in Guanyindong Nature Reserve was investigated. 169 families of vascular plants were found in the reserve. There are 498 genera and 857 species, among them, there are 23 families, 32 genera and 49 species of pteridophytes, and there are 146 families, 466 genera, 808 species of seed plants. There are 9 species of second-class protected plants. There are 234 species of vertebrates belonging to 89 families and 33 orders. There are 11 species of animals under national secondary protection. The ecological sensitivity assessment of Guanyin Dongdong Nature Reserve was carried out. The distribution and habitat status of protected animal and plant resources were investigated. On the basis of the analysis of habitat condition of protecting animals and plants, the index system of sensitivity evaluation of protecting animals and plants was established, and the habitat sensitivity of protected animals and plants was evaluated. Secondly, on the basis of single factor evaluation, the ecological sensitivity of nature reserve was evaluated. (4) based on the evaluation results, the ecological functional zoning of nature reserve was carried out, and the corresponding suggestions were put forward.
