桐柏山水源涵养国家重点生态功能区生态环境遥感监测

Remote sensing monitoring of ecological environment in the national key ecological function area of Tongbai mountain water conservation

围绕国家生态文明建设需要,本文选取了河南省桐柏水源涵养国家重点生态功能区为研究区,利用现代遥感技术开展了生态功能区生态环境遥感监测研究。监测结果表明:2011~2016年5年期间,受人类活动影响,桐柏山水源涵养生态功能区自然生态环境要素向人工生态环境要素转变,自然生态环境要素中的林地、草地、湿地和水域面积都有所减少,减少比例分别为0.61%、0.85%、0.01%和0.03%;人工生态环境要素中的耕地和建设用地面积都有增加,增加比例分别为0.97%和0.52%,人工生态要素之间互相转换,但耕地转换为建设用地的比例较高。

This paper selected the national key ecological function area of Henan Tongbai mountain water conservation area as its research area around the needs of national ecological civilization construction, and carried out the remote sensing monitoring research on the ecological function area by modern remote sensing technology. The monitoring results show that： during the 5 years from 2011 to 2016, the natural ecological environment elements of Tongbai mountain water conservation ecological function area were transformed into artifcial ecological environment elements which infuenced by human activities, the area of forest, grassland, wetland and water area which in the natural ecological environment are reduced, as well as the reduction ratio is 0.61%, 0.85%, 0.01% and 0.03%; The area of cultivated land and construction land in the factors of artifcial ecological environment have increased, and the increase ratio is 0.97% and 0.52% respectively.The conversion between the artifcial ecological factors to each other, but the proportion of cultivated land to construction land is much higher.
