基于GIS的吉林省景观生态学评价研究

Study on GIS-based Landscape Ecological Assessment of Jilin Province

景观生态是一种很重要的环境特征。运用GIS技术以及国外最新的景观结构分析软件Fragstats 3.3,选取软件中10个指标,计算了吉林省1980年至2000年各景观地带的景观结构指标,并对其近20a间的景观结构变化进行了分析研究,从而有助于揭示吉林省的景观结构特征和景观演变规律。

Landscape ecology is a very important environmental characteristic. With the help of ArcGIS 9.2 and FRAGSTATS 3.3, the newest foreign landscape structural analysis software, ten indexes selected from the software were used in the calculation of the landscape structural indexes of Jinling Province from 1960 to 2000 and analysis was made of the change in its landscape patter, helping disclose the landscape structure characteristics and landscape evolution law.
