辽宁省抚顺市生态功能区划

[目的]进行生态功能区划,协调经济发展与生态保护之间的矛盾,实现生态环境的分区管理。[方法]以辽宁省抚顺市为研究区,针对其实际生态环境特征,在传统评价指标中引入区域养殖敏感性评价体系,运用ArcGIS 10.1,对抚顺市水源、土壤、生物等方面的生态环境敏感性和生态服务功能进行评价,然后,采用地理相关法进行生态功能区划,并比较功能区服务功能差异,建立分区管理方案。[结果]研究区敏感性主要为轻度和不敏感,呈"爪"字型相间分布。极敏感和高敏感区主要为老虎台和龙凤矿区及地势陡峭的山坡(共约占1.08%);生态系统服务功能重要性的分布特点与地势分布具有相似性。极重要区主要分布生态系统多为森林的东南地区(约占79.46%)。[结论]抚顺市属于常温带湿润针阔混交林生态区,分为2个生态功能亚区和8个生态功能区,根据功能区服务功能差异将其分为生态保育区、生态恢复区和生态禁止区。

Ecological Function Regionalization of Fushun City, Liaoning Province

[Objective] To regionalize the ecological functional zoning and coordinate the contradiction between economic development and ecological protection in order to realize the regionalization management of ecological environment.[Methods] Fushun City was taken as the research area, a regional aquaculture sensitivity assessment system was introduced into traditional evaluation indicators according to its actual ecological environment characteristics, and ArcGIS 10.1 software was used, to evaluate the ecological environment sensitivity and ecological service function of water source, soil and biology in Fushun City. Then, the method of geographical correlation was used to regionalize the ecological function zoning, to compare the service function difference of functional areas, and to set up the partition management plan.[Results] According to the analysis, the sensitivity of the study area was mainly mild and insensitive, showing a "claw" pattern. The extremely and highly sensitive areas were mainly the Laohutai and Longfeng mining areas, and the steep slopes (approximately 1.08% in total). The distribution of the importance of ecosystem service was similar to the topography distribution. The major ecosystem of the most important areas was forests in the southeastern part of the country (about 79.46%).[Conclusion] Fushun City belongs to normal temperate and theropencedrymion ecological areas and is divided into two ecological function sub-areas and eight ecological function areas. According to the functional differences, it can be divided into ecological conservation zone, ecological restoration zone and ecological prohibited zone.
