| 摘 要： | 选取贵州省清镇市近郊村域王家寨地区为研究对象，在GIS支持下,利用该区域1963年、1982年、2005年、2010年和2015年5期土地利用图形数据叠加分析,提取出研究区50余年来的土地利用/覆盖信息，并结合相应的社会经济统计数据，分析了其驱动力因子，其结果表明:(1)1963—2015年间，土地覆盖类型的总体变化为高被草地和平坝旱耕地明显减少，低被草地、农村居民点、工矿用地、公路用地面积大幅增加，其中，平坝旱耕地有向经济效益更高的土地利用方式转变的趋势；（2）景观格局演变的总体趋势是:自1963年起，斑块数量、斑块密度持续增加，到2015年呈下降趋势，而最大斑块指数逐年减小，形状趋于不规则，同时，近50年景观的多样性指数持续增加；（3）区内土地利用/覆盖和景观格局呈阶段性变化，从1963年到2005年，坡地土地利用活动较强，2005年后，平地土地利用强度增加、农业逐渐转型、聚落持续扩展；（4）区内土地利用及景观格局的变化主要受经济、人口和政策因素的影响。

| Abstract: | It is of great significance to explore the influence of human activities on land use and landscape pattern evolution in small-scale in karstic mountain villages. In this study, the suburb Wangjiazhai village area of Qingzhen City was selected as a case. With the support of GIS,using the data superposition analysis of the land use figures in 1963, 1982, 2005, 2010 and 2015，land use /cover information of more than 50 years was extracted to establish the models of land use area change, single land use type dynamics, regional land use comprehensive dynamics and the model of land use transfer matrix. At the same time, the spatial and temporal characteristics of land use / cover and landscape pattern change are systematically analyzed by selecting different indices at the type level and landscape level. Combined with the result of socioe-conomic statistics the results showed that, (1) In 1963-2015, the main change of land cover in the area was characterized by the significant decreases of high-cover grassland and valley dry farmland; in the same period, low cover grassland, and the areas for rural resident, industry and mine land and road construction increased; of them the use of valley dry farmland tended to yield higher economic interests. (2) The overall trend in the evolution of the landscape pattern was that the number and density of land plots have grown since 1963 but decline since 2015 the largest patch land index decreased year by year and tended to be irregular in shape. At the same time, the landscape diversity index has continued to increased over the last 50 years. (3) Land use/cover and the landscape pattern in the study area changed periodically, from 1963 to 2005, the land use activities in the area were stronger. After 2005, the land use intensity increased, the agriculture gradually transformed and the settlement continued to expand.(4) The change of land use and landscape pattern in the study area is mainly influenced by economic, population and policy factors. Land use and landscape pattern should be enhanced to meet the increasing population and the rising consumption demand. |
