尕海则岔自然保护区地表覆盖遥感监测

Remote Sensing Monitoring of Land Cover in Gahai Zecha Nature Reserve

通过获取2015年、2019年地表覆盖类型信息,分析了尕海则岔自然保护区内地表覆盖现状和变化情况。结果表明4 a间尕海则岔自然保护区地表覆盖变化不明显,但不同地表覆盖类型之间的转换关系复杂,且速度不一[1]。尕海则岔自然保护区草地面积减少最多,房屋建筑区和构筑物面积增加相对较多。减少的草地主要是转换为房屋建筑区、构筑物、道路和人工堆掘地等人工地表[2]。

Based on the land cover type information in 2015 and 2019,we analyzed the current situation and changes of land cover in Gahai Ze-cha Nature Reserve.The results showed that the land cover changes in Gahai Zecha Nature Reserve was not obvious in the past four years,but the transformation relationship between different land cover types was complex and the speed was different.The grassland area of Gahai Zecha Nature Reserve decreased the most,while the building area and construction area increased relatively more.The reduced grassland was mainly converted to artificial surface,such as construction area,buildings,roads and artificial land.
