| 摘 要： | 以遥感影像和野外调查为数据源,3S为技术手段,对1993-2009年间贵州省黔东南苗族侗族自治州景观空间格局进行动态分析和综合研究.结果表明:研究时段内黔东南州景观斑块数量增加,平均斑块面积减小,景观结构破碎化整体上有增加的趋势,主要表现为多样性指数、分维数增大,聚集度、均匀度减小,在空间分布和景观类型上局部变化不同于整体的表现；自然地理条件、人口增长、政府政策是导致景观格局变化及其区域差异的主要驱动因素；随着经济发展、农田开发等人类干扰的不断增加,生态环境保护与经济开发之间的矛盾将会逐渐突出.

| Abstract: | Based on the Landsat TM/ETM images and field survey data,the change of landscape pattern,landscape dynamics and its driving factors from the year 1993 to 2009 in Qiandongnan Prefecture were studied with the aids of 3S techniques.The results indicated that: the number of landscape patches increased,mean patch area reduced,and fragmentation indices of landscape pattern had an increasing trend in last 16 years.The fractal dimension,diversity,contagion and even indices in Qiandongnan Prefecture gradually decrea... |
