摘要
景观格局、生态过程和时空尺度是景观生态学研究中的核心内容。本文以云南省昆明市呈贡区为例,利用2001年与2016年两期遥感影像,分别是landset7和landset8卫星影像数据,对呈贡区的地类景观格局类型的形状、比例和空间配置的时空变化进行研究,得出了影响呈贡区地类景观格局变化的物质循环、能量流动和信息传递的主要驱动力,同时从地类景观格局类型的分布与变化方向分析了呈贡区在土地利用中存在的问题,并提出相关的发展建议。
Landscape pattern, ecological process and time and space scale are the core contents of landscape ecology research. In this paper, taking Chenggong District, Kunming City, Yunnan Province as an example, using two remote sensing images from 2001 and 2016, i.e. the landset7 and landset8 sat-ellite image data respectively, the shape, proportion and spatial configuration of the landscape pattern, and the temporal and spatial changes were studied, and the main driving forces of the material circulation, energy flow and information transmission were analyzed, and the distribution and change direction of the landscape pattern were analyzed. This paper uses the existing problems, and puts forward the relevant development proposals.
