中文摘要：
由从三个时期使用遥感图象(1980， 1995， 2000 ) 并且与 GIS 和 RS 的支持，到 2000 的吉林省 from1980 的风景元素的空间信息被解释并且提取。用风景的模型，象差异，破碎，和平均数那样的索引修正分数维的尺寸，省的风景模式的动态时间空间的变化被分析。结果：农田和林地是主要风景类型，并且林地成为了一个风景矩阵；在学习区域，风景不均匀的被散布，并且有低异质，简单生态系统结构和荒谬的风景模式的一个趋势。也有补丁和 strongself 类似的简单空间形状，并且以动态变化分析，补丁形状趋于更简单；从 1980 ～ 2000，整体的风景破碎稍微低、改变。根据风景元素被担心，草地，水区域，为居住区域的陆地和工厂设备的破碎是相对低的；为居住区域和工厂设备的陆地分发被驱散；并且农田和林地最被集中—趋势将继续的一个指示。在人的活动，本地政策，地区性的气候和环境变化之中的全面效果导致了结果。
英文摘要：
By using remote sensing images from three periods （1980, 1995, 2000） and with the support of GIS and RS, the spatial information of landscape elements of Jilin Province from 1980 to 2000 was interpreted and extracted. Using models of landscape indices such as diversity, fragmentation, and mean patch fractal dimension, dynamic spatio-temporal changes of landscape patterns of the province were analyzed. The results： ① cropland and forestland were the main landscape types, and forestland became a landscape matrix; ② in the study area, landscapes were distributed unevenly, and there was low heterogeneity, a simple ecosystem structure and a tendency of irrational landscape patterns. There were also simple spatial shapes of patches and strong self-similarities, and in terms of dynamic change analysis, patch shapes tended to be more simple; ③ from 1980 to 2000, holistic landscape fragmentation was low and changed slightly. As far as landscape elements were concerned, the fragmentation of grassland, water area, land for residential area and factory facilities was relatively low; land distribution for residential areas and factory facilities was dispersed; and cropland and forestland were most concentrated - an indication that the trend will continue. Comprehensive effects among human activity, local policy, regional climate and environmental change led to the results.
