【摘要】：旨在探索如何构建一种生态与经济发展兼顾的建设用地管制分区工作体系。以扬州市为例,选择防洪、水土保持、生物保护、乡土文化保护和游憩安全5个要素构建区域多层次综合生态安全格局,利用神经网络CA模型模拟无生态约束下的区域城镇建设用地扩展格局,将二者耦合得到优先建设区、有条件建设区、调整建设区、限制建设区和禁止建设区,并为每类管制区编制相应的管制规则。结果表明:①利用景观安全格局与城镇建设用地扩展格局耦合来进行建设用地管制区划分,优先考虑生态环境保护,再进行建设用地的安排,实现了生态与经济的双赢;②通过调整建设区的划定,为地方政府提供了新增建设用地适宜调整的区域,在建设用地管制的基础上,给予地方政府充分的自主权。
[Abstract]:The purpose of this paper is to explore how to construct a system of construction land management and zoning which takes ecological and economic development into account. Taking Yangzhou City as an example, five elements of flood control, soil and water conservation, biological protection, local culture protection and recreation security are selected to construct a multi-level comprehensive ecological security pattern in the region. The neural network CA model is used to simulate the expansion pattern of regional urban construction land without ecological constraints, and the two models are coupled to obtain priority construction areas, conditional construction areas, adjustment construction areas, restricted construction areas and prohibited construction areas. Corresponding control rules are prepared for each type of control area. The results show that using the coupling of landscape security pattern and urban construction land expansion pattern to divide the control area of construction land, priority is given to ecological environment protection, and then the arrangement of construction land is carried out, which realizes the win-win situation between ecology and economy. (2) by adjusting the delineation of the construction area, the local government has been provided with an area suitable for the adjustment of the newly added construction land, and on the basis of the control of the construction land, the local government has been given full autonomy.
