黄河流域典型农业县土地利用演变及其生态环境效应
Evolution of Land Use and Its Eco-environmental Effects of Typical Agricultural Counties in Yellow River Basin
摘要
Abstract
Ecological protection and high-quality development in the Yellow River Basin has become a national strategy.For the typical agricultural counties in the Yellow River Basin,where agricultural production is the main focus,the contradiction between production,life and ecological land is more prominent,and the coordinated development of"production-living-ecological space"is more important.Studying the ecological and environmental effects of land use evolution can provide scientific basis and reference for the national strategy.This paper used area-weighted method to accurately measure the difference of ecological environment quality of different secondary land use spaces in different years,and quantitatively analyzed the ecological environment effect of land use evolution by combining land use transfer matrix and ecological contribution rate.The results showed that from 2009 to 2020,land use transformation in Qihe County was mainly between forest ecology and agricultural production space,and between agricultural production and water ecological space.The comprehensive quality index of ecological environment increased from 0.397 to 0.398 from 2009 to 2015,and from 0.398 to 0.405 from 2015 to 2020.In general,the comprehensive index of ecological environment quality of Qihe County continued to rise slightly from 2009 to 2020 and was generally improved.The results were in line with the development reality of Qihe County as the main grain-producing county.For the typical agricultural production county in the Yellow River Basin,the transition from agricultural production and industrial-mineral production space into woodland ecological and water ecological space was the main factor that promoted the improvement of eco-environmental quality,and the transitions including from woodland ecology and water ecology into agriculture and industrial-mineral production,and from agricultural production into industrial-mineral production space led to the deterioration of eco-environmental quality.关键词
