摘要
基于2009-2015年4期遥感影像数据,综合运用监督分类和目视修正相结合的方法以及景观格局指数,对勐海县景观格局变化特征及其驱动机制进行了分析。结果表明:2009-2015年,勐海县林地面积减少了134.9 km^2,主要是转换为园地和旱地;农田和水域面积减少了64.14 km^2,主要是转换为旱地、林地和园地;建设用地面积增加了18.92 km^2,主要是由旱地、林地和农田转换而来。林地景观的连通性较好,在总体景观中占主导作用,旱地、园地和水域的景观破碎化程度降低,农田、建设用地的景观破碎度在逐年变高;景观破碎化程度增大,各种景观类型在面积分布上更加均匀;人口增长和经济发展是影响勐海县景观格局变化的主要驱动机制。
Based on the remote sensing image data of 2009 to 2015, the combination of supervised classification and visual correction and the landscape pattern index were used to analyze the changes of landscape pattern and its driving mechanism in Menghai. Results show that from 2009 to 2015, the forest land area of Menghai has decreased by 134.9 km^2, mainly converted into garden land and dry land. The area of farmland and waters has decreased by 64.14 km^2, mainly converted into dry land, woodland and garden land. The construction land area has increased by 18.92 km^2, mainly from dry land, woodland and farmland. The connectivity of the woodland landscape is good, and it plays a leading role in the overall landscape. The degree of landscape fragmentation in drylands, gardens and waters is reduced, and the landscape fragmentation of farmland and construction land is increasing year by year. The degree of landscape fragmentation is increased, and various landscape types are more evenly distributed in area. Population growth and economic development are the main driving mechanisms affecting the landscape pattern change in Menghai.
