上海半城市化区域自然景观生态格局优化设计的途径

半城市化现象是城市化过程中的必然阶段,上海半城市化现象具有特殊性和示范性,上海半城市化区域自然景观格局的研究途径是:以上海半城市化区域时空演变的特征和机理探索为基础,以上海半城市化区域生态景观格局优化和生态功能空间重构为目标,综合运用3S技术、土地时空演变模型分析技术、景观动态格局与生态过程关系分析技术和生态格局优化模式设计技术等方法,包括:1、上海半城市化区域空间识别,从结构、变化、景观和体制4个层面确定上海半城市化区域的范围和主要类型;2、上海半城市化区域自然景观时空演变动态及驱动力分析:综合运用土地演变的多个分析模型,探究自然景观时空演变过程和驱动力机制;3、上海半城市化区域自然景观格局与生态过程关系研究:分析上海半城市化空间扩展与自然景观生态过程之间的关系,构建上海半城市化空间拓展的生态机制;4、上海半城市化区域自然景观生态格局优化设计:综合自然景观中各类土地覆被类型的生态功能和社会、经济功能,综合分析各类生态要素,研究样区内的生态功能区、生态敏感区、生态邻里、生态要素配置的类型划分和分析,研究上海半城市化区域自然景观生态格局优化设计。

The Optimizing Design Approaches of Natural Landscape Ecology Patterns of Peri-urban Area in Shanghai

Peri-urbanization is the necessary stage in the urbanizing processes,the peri-urbanization in Shanghai is very different from other regions of China,the approaches of natural landscape ecology patterns of peri-urban area in Shanghai is as follows: firstly,identify of peri-urban area of Shanghai need be made from space structure,transformation,landscape and politicals;second,analyses of natural landscape space-time transformation and drive force of peri-urban area of Shanghai need be made by using various land transformation processe models,land transformation drive force models;third,the relationship between natural landscape pattern and ecological processes in Shanghai need be got according to the ecological environmental situations and Shanghai developing planning;then,the optimizing design of natural landscape ecology patterns of peri-urban area in shanghai can be made by synthesising of the ecological functions,social functions and economic functions of various land-covers and analysing of ecological function area,ecological sensitive area,ecological neighborhood,ecological strategical point.
