基于生态系统服务功能和生态敏感性的自然生态空间管制分区研究

自然生态空间分区管制是国土空间管制的重要组成部分,也是国内外生态环境研究的热点。针对国内自然生态空间用途管制暂处于试点阶段,有关管制的方法有待进一步探究的情况下,旨在通过江西省自然生态空间管制分区,为实现合理保护自然生态资源,促进自然生态系统健康有序发展提供参考。以江西省为研究对象,借助GIS空间分析技术,通过生态系统服务功能重要性和生态敏感性评价,构建二维关联判断矩阵,进行自然生态空间管制分区,并以此提出相关的管制建议。结果表明:江西省自然生态空间总面积为117924.67 km²,约占全省总面积的70.66%,从空间上可划分为高重要高敏感区、中度重要敏感区和低重要低敏感区3种类型区;其中,高重要高敏感区以生态保护和生态修复为主,实施严格的区域准入措施;中度重要敏感区可依托区域生态资源优势,合理开展以维护、改善生态系统服务功能为主要目的生态经营活动;低重要低敏感区允许在不破坏生态系统结构和功能的前提下,适度开展一定规模的生产建设活动,减少污染排放,增强区域生态功能。全省16个国家自然保护区基本位于高重要高敏感范围内。基于生态系统服务功能与生态敏感性的自然生态空间...

The natural ecological spatial management zoning based on ecosystem service function and ecological sensitivity

Natural ecological spatial management is an important part of national spatial management, and it''s also a hot topic of eco-environmental research in China and abroad. Under the background of the domestic natural ecological spatial use management temporarily being in the pilot stage and the method of management needing to be further explored,this paper aims to provide a reference for the reasonable protection of natural ecological resources and promote the healthy and orderly development of natural ecosystems based on natural ecological spatial management zoning in Jiangxi province.After evaluating of ecosystem services importance and ecological sensitivity, this paper discussed methods of natural ecological spatial management zoning, in Jiangxi province by GIS spatial analysis technology.The results show that the area of the natural ecological space is 117924.67 km², accounting for 70.66% of the total area of Jiangxi province, are divided into three types by the method of two-dimensional judgment matrix analysis.Different approach of measurement is suitable for different types of areas.Among them, the ecological protection and ecological restoration are the main task for high-importance and high-sensitivity area. In the medium-importance and medium-sensitivity area, it is expected to rely on the regionally ecological resources to carry out ecological operation activities with main purpose of maintaining and improving the ecosystem service functions.For the low-importance and low-sensitivity area, the moderate development of production and construction activities was allowed in certain scale, to reduce pollution discharge and strengthen regional ecological function. However, this can only be done without destroying the structure and function of the ecosystem.Besides, the research indicated that all 16 national nature reserves were in the range of high-importance and high-sensitivity area.The natural ecological spatial management zoning and the general land use planning of Jiangxi province complemented each other. Natural ecological spatial management zoning that based on the ecosystem service function and ecological sensitivity, could provide new ideas for natural ecological spatial management, thus effectively promoting the implementation of control work.
