| 摘 要： | 根据地学信息图谱理论与地球空间信息认知理论,利用西安市1988、2000年两期遥感影像,分析了西安市1988-2000年间土地利用时空演变过程;利用PSR模型构建了西安生态安全评价指标体系,借助AHP法确定权重,采用遥感影像确定模型中的自然组分数据,结合社会经济统计数据,对生态安全动态进行了尝试性评价;将土地利用图与生态安全评价图做叠置分析,得到了生态安全状态与土地利用格局间的内在联系。

| Abstract: | Based on the geo-information atlas theory and the terrestrial information cognition theory,by using remote sensing imagee in 1988 and 2000,the land use change process of Xi'an during 1988-2000 years was analyzed.Ecological security evaluation indicator system of Xi'an was constructed by using the PSR model.With the aid of the AHP to determine weight,the remote sensing images to determine natural component data,and social economic statistical data,the experimental evaluation was carried out for ecological security trend.At last,making an overlay analysis between land use chart and ecological security evolution map,the inner link between ecological security condition and land use pattem was obtained. |
