自然生态空间用途管制分区划定研究——以平潭岛为例

研究目的:在明确自然生态空间内涵和分类的基础上,探讨自然生态空间用途管制分区划定的逻辑框架和技术方法,提出自然生态空间分类、分级管制规则。研究方法:文献综述与GIS空间分析。研究结果:根据不同自然生态系统类型及其空间分布特征将自然生态空间类型划分为森林生态空间、草地生态空间、湿地生态空间和荒地生态空间;基于景观功能识别并按不同管控等级将自然生态空间管制类型区划分为红线区、橙线区和黄线区;同时,依据不同地块主要功能进一步确定自然生态空间用途管制分级,划定用途管制分区结果。研究结论:基于"区域主体功能—景观主导功能—地块主要功能"的自然生态空间管制分区划定逻辑框架,可为构建以功能分类、用途分区、管控分级为导向的自然生态空间用途管制体系提供理论依据和实践借鉴。

Research on Ecological Space Classification and Land Use Zoning Regulation: A Case Study of Pingtan Island

The purpose of this paper is to explore the basic framework and methods for ecological space classification and land use zoning regulation based on identifying the concept and connotation of natural ecological space. The methods of literature review and spatial analysis with GIS are used. According to different types of ecosystem and their spatial pattern characteristics, the ecological space is classified into four types: forest ecological space, grassland ecological space, wetland ecological space and wasteland ecological space. The types of land use zoning for ecological space are divided into red-line subarea, orange-line subarea and yellow-line subarea based on different degrees of land use regulation associated with local major landscape function levels. Meanwhile, each zone of land use regulation, the degree of each zoning regulation, basic principles and rules are formulated according to the major functions of different types of ecological space plots. In conclusion, with the basic framework for different scale of regional-landscape-patch functions, the paper can provide the theoretical basis and practical reference for the construction of ecological space classification and land use zoning regulation systems oriented by functional classification, land use zoning and regulation grading.
