摘要
以山东省枣庄市2010年遥感数据为主要数据源,根据国家标准的土地利用现状分类系统,采取计算机解译与目视解译相结合的方法提取枣庄市土地利用信息现状,结合枣庄市1991、1996年的土地利用信息,分析枣庄土地动态变化情况。分析结果表明,枣庄市耕地面积在逐年减少,大部分转化为建设用地;因水土流失、土地污染等问题导致的未利用的土地面积在增加,废旧河道未得到充分利用;林地、园地、牧草地占土地总面积的比例较低。为了实现土地可持续发展,枣庄市须加强耕地保护力度,合理控制建设用地规模,结合其自然条件合理调整土地利用结构和布局,修复塌陷地、利用废旧河道,充分利用闲置用地。
Based on remote sensing data of Zaozhuang City in 2010,according to the national standard of current land use classification system,by using the computer interpretation and visual interpreting method to extract land use information status,and combining land use information of Zaozhuang in 1991 and 1996,the land dynamic change was analyzed.The results showed that farmland area gradually decreased,most of them converted into construction land;because of soil erosion and land contamination,unutilized land area increased;woodland,garden land,grassland accounted for low proportion of the total.In order to achieve land sustainable development,Zaozhuang City should strengthen protection degree for farmland,control construction land scale.According to its natural conditions,adjust land use structure properly.
