基于土地生态演替的区域生态格局构建

城市生态建设应采取主动的生态修复与建设措施,积极打造适应区域生态循环和演替过程的生态格局,从而增强生态系统自身稳定性,提高其相应生态服务功能。根据对以往生态格局规划案例的总结发现,现有规划模式对土地的动态变化考虑不足,对主导土地自然演替规律的区域综合自然地理过程缺少分析,因而构建的生态格局体系可能存在着生态稳定性差、绩效成本高的问题。本文针对这一问题,以河南省汝州市王寨工业集聚区规划为例,通过推断土地的自然演替规律,结合土地利用现状数据,对区域的生态适宜性进行评价,以期在适应区域土地演替规律的基础上,构建区域生态格局。

A Method to Construct Urban Ecological Pattern Based on the Theory of Land Succession: A Case Study of Wangzhai Industrial Distribution Planning, in Ruzhou City of Henan Province

In the urban ecological construction,rather than only protect the existing ecological space only,we should pay more attention on ecological recovery and ecosystem construction in order to build an ecological pattern which will fit the regional ecological process,and may improve the stability and functions of regional ecosystem.In this article,we found out a problem that the recent method of ecological pattern building had a short consideration on integrated physical geography process and land succession,and that might cause the instability of ecological pattern and the high cost of ecosystem construction.Aiming at this problem,we took the plan of Wangzhai industrial distribution in Ruzhou city of Henan province as a case study.Through analyzing integrated physical geography process,we predicted the results of land succession first.Then,we made a ecology suitability evaluation with the date of recent land use and the results of land succession.Finally,we built an ecological pattern which might fit the integrated physical geography process and the land succession.
