上海城市景观格局分析研究

An Analysis of the Urban Landscape Pattern in Shanghai

文章利用遥感影像解译的土地利用数据研究了上海快速城市化阶段的城市景观变化特征.结果表明:人类干扰导致了景观的破碎化程度增加,斑块隔离程度加大,景观多样性增大;社会经济的快速发展侵占了大量生态用地,使一些对城市生态环境起重要保护作用的绿地、林地、耕地、园地、水域等资源永久丧失;摊大饼式的城市扩张和无序蔓延还加剧了城市周边生态景观的破碎化程度,阻塞了一些重要动物的迁徙廊道,从而影响到生物多样性保护.

This paper, making use of the remote sensing use, is to study the urban landscape variation in Shanghai image interpretation of the data phase concerning land in the process of rapid urbanization. The results show that human interference has led to increased landscape fragmentation, the increasing degree of patch isolation, and the increased landscape diversity. The rapid social and economic development has occupied a large amount of ecological land, resulting in a permanent loss of vegetation, woodland, cultivated land, gardens, territorial waters and other resources that, otherwise would play an important protective role in the city＇s ecological environment. The piestyle urban expansion and sprawl around the city have also increased the degree of ecological landscape fragmentation, blocking some important migration corridors for animals, and thus affecting the biological biodiversity conservation.
