Research on Wetland Change in Qinzhou Municipal Districts Based on Tupu Analysis
摘要
Abstract
Objective The wetland dynamic change in Qinzhou municipal districts was stud-ied,and the reason and speed of change were investigated,in order to provide typical case and demonstration for wetland dynamic change by the methods of Geo-information Tupu.[Methods]Based on TM remote sensing image of Qinzhou municipal districts in 1990,2000, 2010,spatial distribution maps was extracted by spectrum-photometric method and manual interpretation method.Then,the methods of Geo-information Tupu was used to analyze the wetland dynamic change.[Results](1)From 1990 to 2010,river,lakes and reservoirs,re-spectively,reduced 958.52 hectares and 1718.93 hectares,mainly transferred to non-wet-land and shrimp ponds.(2)From 1990 to 2010,shrimp ponds increased 4557.87 hectares, mainly from non-wetland and river.(3)From 1990 to 2000,mangrove area increased 468.51 hectares,mainly from wet-land and river.From 2000 to 2010 mangrove area reduced 104.67 hec-tares,mainly transferred to non-wetland and shrimp ponds.(4)From 1990 to 2000 paddy field increased 1506.98 hectares.From 2000 to 2010 paddy field reduced 1226.89 hectares.[Conclusion]The protection in wetland of Qinzhou municipal districts is effective and the wetland area shows a growing trend.关键词
