以GIS技术为手段,研究了睢宁县土地利用的格局特征,得出以下结论:1)睢宁县土地利用类型中,耕地面积占比最大,其次是居民点及工矿用地.2008~2013年,睢宁县耕地和水域面积减少,居民点及工矿用地面积增加.2)睢城镇、庆安镇、双沟镇和姚集镇土地利用变化远大于区域平均水平,邱集镇、古邳镇、沙集镇和官山镇远小于区域平均水平.3)研究区土地利用程度呈现为南部地区较高,北部地区较低的格局特征.睢宁县政府驻地及其附近的乡镇,表现为土地利用程度高值空间集聚分布特征,睢宁县北部的姚集镇境内及古邳镇和魏集镇2镇的交界处形成了低值集聚区.
The pattern characteristics of land use in Suining are studied in this paper by means of GIS technology.Conclusions are drawn as follows:1)The arable land area accounts for the largest proportion,followed by residential and industrial land.From 2008 to 2013,the coverage of arable land and water area decreased,while residential and industrial areas increased.2)The land use change in Suicheng Town,Qing'an Town,Shuanggou Town and Yaoji Town is far greater than the regional average level,but that in Qiuji Town,Gupi Town,Shaji Town and Guanshan Town is far smaller than the regional average.3)The land use degree in the south of Suining is high,while it is low in the northern region.The spatial distribution of land use in the investigated district tends to cluster.Some portions of the investigated district display a spatial structure featuring cold areas and hot areas.Hot areas are mainly located in the middle of the investigated area,namely,areas near Suicheng Town,where spatial agglomeration distribution of high values on the land use degree is observed.Cold areas are located in the western part of Yaoji Town and the junction part of Gupi Town and Weiji Town,which are low value zones on the land use degree.
