| 摘 要： | 利用山西省娄烦县1995~2004年土地利用数据和2004年数字化土地现状图,采用GIS技术与景观生态分析技术相结合的方法,对该县土地利用/土地覆被动态变化和景观空间格局进行分析。研究结果表明:耕地、牧草地和水域呈持续下降趋势,建设用地、工矿和交通用地呈上升趋势。各景观要素的破碎化趋势是面积越大,破碎度越大,优势度减小,主要的干扰因素是人类活动。分离度指数在一定尺度上是交通和工矿业用地最大,耕地、林地、牧草地相对较小。

| Abstract: | Based on the dynamic datum of land use in 1995 to 2004 and the indexes of landscape pattern and the digital map in 2004,the change of the land use and conversion and its pattern was studied using ARCVIEW3.2,SPSS11.0 and Excel.The results showed that cropland,grassland and water land decreased and constructive land were increased.The trend of the landscape elements fragmentation index was increased with the increasing area,while the landscape dominance index was decreased due to the human activities.In the scale,the isolation index of the traffic land and industrial land relatively was higher than that of the cultivatable land and grassland. |
