摘要
以河南省2000年、2010年和2020年LUCC数据为基础,运用土地利用动态度对河南省2000—2020年土地利用变化情况进行分析,量化处理河南省的生态系统服务价值总量及单项生态系统服务价值,并分析其敏感性程度。研究结果表明:河南省2000—2020年耕地、林地和草地面积均明显减少,建设用地土地利用动态度较大,人类活动对生态系统的干扰程度增强。河南省生态环境效应呈波动下降趋势,且对各类土地利用生态系统服务价值敏感性较小,但是单项生态服务价值结构较为稳定。
Based on henan 2000, 2010 and 2020 LUCC data, the land use dynamics were used to analyze the land use change in Henan Province from 2000 to 2020, and the total value of ecosystem services and the value of individual ecosystem services in Henan Province were quantitatively processed, and the sensitivity of them was analyzed. The results show that the area of arable land, forest land and grassland in Henan Province decreased significantly from 2000 to 2020, the land use dynamic degree of construction land was relatively large, and the degree of interference of human activities on the ecosystem was enhanced. The overall ecological and environmental effects of Henan Province show a fluctuating downward trend, and the sensitivity to the value of various land-use ecosystem services is small, but the value structure of individual ecological services is relatively stable.
