东莞市景观生态演化特征的分析

利用多时相遥感手段，对东莞市的景观演化特征进行了回顾性分析，重点研究不同景观要素从1986～1994年的变化情况，探讨景观结构和功能变化与东莞市社会经济发展之间的对应关系。研究表明，高强度土地资源开发利用是东莞市景观变化的直接驱动因素，生物过程在景观动态变化过程中，居于次要地位；景观演化的基本格局是城市要素迅速膨胀，农业和自然要素则不断减少；由于缺乏必要的景观结构和功能的相互适应设计，在东莞市景观演化过程中，存在一些潜在的生态问题。初步探讨了东莞市景观生态保护的基本途径

Analysis of landscape ecological changing characteristics of Dongguan City

In this paper, the multi time remote sensing method was used to deal with the review analysis of the landscape changing characteristics of Dongguan City. The emphasis of this study is the spatial changing conditions of varies landscape elements from 1986 to 1994;and the relations between the landscape structural and functional changes and the Dongguan social and economic developments were also discussed. Study results indicate that land resource utilities of high density are the direct driving force of landscape changing, and the natural processes just hold the second driving position in the changing of Dongguan. The basic landscape changing pattern in this area is that the urban elements increase quickly with the agricultural and natural elements decreasing gradually. Due to lacking a necessary design for the coordination of landscape structure and function, there are some potential ecological problems in Dongguan landscape changing process in recent years. Finally, we initially discussed the landscape ecological protection methods for Dongguan City.
