摘要:
基于近10年来我国城市(群)地区生态保护红线划分的实践经验,结合环境总体规划的探索,提出了一套城市生态保护红线体系与划分方法。首先,按照"识-评-落-合"的技术流程,划定城市生态功能红线。其次,通过识别大气环境和水环境的重要性,敏感性和脆弱性,划定环境质量红线。第三,基于合理的模型方法计算大气环境、水环境和自然资源承载力,分析测算环境资源开发上限。最后,借助GIS软件实现这三条红线的空间叠加,综合划分出生态保护红线。上述生态保护红线体系,与现有的各部门空间和资源管理制度能进行充分有序的衔接,可以作为促进新型城镇化健康发展的资源环境管理基础平台。
Abstract:
In this paper, based on the recent ten-year experiences in delimitation of urban (urban agglomeration) ecological protection line in China, a set of urban ecological protection line system and delimitation methods is proposed in combination with the exploration of general environmental planning. Firstly, according to the technical process of "identification-evaluationimplementation-integration", urban ecological function line is delimited. Secondly, environmental quality line is delimited by identification of the importance, sensitivity and vulnerability of atmospheric and water environment. Thirdly, top limits of environmental resource exploitation are analyzed and calculated on the basis of the bearing capacities for atmospheric environment, water environment and natural resources. Finally, by use of GIS software, a spatial overlap of the three lines is realized and therefore the ecological protection line is delimited in a comprehensive way. The above ecological protection line system can be linked fully and orderly with the existing space and resource management of other departments, providing a basic platform of environmental resource management for promoting sound development of new urbanization.
