| 摘 要： | 利用遥感数据，相关专题地图和社会经济统计数据。在GIS的支持下，以位于中国东北农牧交错带的吉林省镇赉县作为典型研究区，探讨了东北农牧交错带土地利用变化影响生态环境演化的机制。运用马尔柯夫模型对镇赉县土地利用变化进行空间统计分析。并从景观生态格局，土地荒漠化和水环境等三方面对土地利用变化的生态环境效应进行了实证分析。

| Abstract: | Zhenlai county in the ecotone between agriculture and animal husbandry in northeast China was taken as a typical area to probe the mechanism of influence of land use change on eco_environment. Remotely sensed data ,relative thematic maps and social_economical statistic data were applied. The land use change and the characteristic parameters of the spatial pattern of the landscape in Zhenlai county were calculated using Markovian model supported by GIS. In the light of landscape spatial pattern, desertion and water environment ,the eco_environment response to land use change was taken into account. As a result ,with the changing of land use, the landscape fraction increased, while the dimension of patches decreased, the desertion and water environment exacerbated severely in Zhenlai county |
