海子山自然保护区生态环境质量评价

海子山自然保护区生态环境独特,珍稀濒危动物富集,但在人类干扰下,其生态环境逐步恶化。本文采用层次分析法,选取自然性、多样性、代表性、稀有性、生态脆弱性、面积适宜性、人类干扰等7项指标对该自然保护区的生态环境质量进行定量评价。结果表明,该自然保护区自然性赋值为4分,多样性赋值为3分,代表性赋值为4分,稀有性赋值为4分,生态脆弱性赋值为3分,面积适宜性赋值为4分,人类干扰赋值为2分,综合评价指数为0.78,生态环境质量较好,但今后仍应加大该区的保护与管理。

Ecological Environment Evaluation on Haizishan Natural Reserve

Haizishan Natural Reserve has special ecological environment and abundant rare and endangered animals, but the ecological environment gradually deteriorated by the human interferenee. This paper selects index of nature, variety, representafive, rare, ecologically fragile, area suitability, and human interference to carry out the evaluation of ecological quality of Haizishan Natural Reserve by using the Analytical Hierarchy Process method. The result shows that the value of nature is 4, the value of variety is 3, the value of representative is 4, the value of rare is 4, the value of ecologically fragile is 3, the value of ares suitability is 4 and the value of human interference is 2. It indicated that the ecological environment equality of the protection zone is good; the evaluation index is 0. 78, but more protection and management should still plough into the Haizishan Natural Reserve.
