| 摘 要： | 利用相关资料并借助RS/GIS方法对20世纪50-70年代的大规模围垦情况进行了初步分析。结果表明:20世纪50年代、60年代、70年代、80年代0.1km2以上的湖泊总量分别是1309个、611个、612个、838个,湖泊总面积分别是8503.7km2、5467.5km2、2934.3km2、2977.3km2。湖泊数量和面积减少与围湖垦殖关系密切,江汉湖区平均面积变化率为65.0%,围垦具有明显的区域差异特征。围湖垦殖与江汉平原湿地演化关系密切,围湖垦殖降低了江汉平原湿地演化的可持续性。 |

| Abstract: | An analysis using RS/GIS and other relevant information was conducted on the large-scale land reclamation in the 1950s-1980s. Results showed that the total number of lakes with an area larger than 0.1 km2 (10 ha) in the 1950s,1960s,1970s,1980s were respectively 1 309,611,612,838 and the total areas of the lakes were respectively 8 503.7 km2,5 467.5 km2,2 934.3 km2,2 977.3 km2. The reduction of number and area of the lakes was closely related with the reclamation and 65% of the plain were under changes. The ... |
