中文摘要：

选择中山市为对象进行实地调查研究,回顾了基塘生态农业发展模式,并利用1990、2000、2013年3期TM遥感影像数据和地理信息系统（GIS）技术获取中山市基塘用地景观变化图,计算各时期基塘用地景观格局指数。结果表明：传统的基塘农业模式正逐渐消失,基-塘的种养模式及其空间比例结构发生重大变化,主要表现为“重塘轻基”现象,即重视鱼塘养殖、轻视基面种植;研究期内基塘用地变化较大,出现先增后减趋势,由1990年的324.69km^2增加到2000年的476.56 km^2,至2013年减少为424.58 km^2;景观格局分析表明,基塘用地景观破碎化程度降低、聚合度上升,这是由于基塘用地得到整治规划、集约化经营的结果。

英文摘要：

Zhongshan was taken as a case study area and the Dike-pond ecological agricultural development model was reviewed. Based on the interpretation of Landsat-TM data（with three digital images taken in 1990, 2000 and 2013,respectively） and GIS technology, dynamic changes of Dike-pond land landscape types were attained and some landscape pattern indices were computed and analyzed. The results showed that traditional Dike-pond agricultural pattern was gradually disappearing with great change of Dike-pond＇s planting and cultivating patterns, also with significant changes of Dike-pond＇s proportion in space structure. The main performance was ＂heavy pond light base＂, which attached great importance to the fish pond aquaculture while despised dike planting. The Dike-pond land changed greatly with the trend of first increasing and then decreasing, which increased from 324.69 km^2 in 1990 to 476.56 km^2 in 2000 and reduced to424.58 km^2 in 2013. Landscape pattern analysis showed that the fragmentation of Dike-pond land reduced and the polymerization rose, which was the result renovated and planed by Dike-pond land.
