摘要
采用改进的当量因子法,对河南新郑市近18 a来土地利用转型及生态系统服务价值进行评估,结果表明:①区域生活生产功能的持续增强是"三生"用地转型的主要方向,增速达41.55%,主要归因于生活生产空间对生产生态空间的侵占。②生态系统服务价值持续下降,尤以2010年后降速明显(-35.63%)。其中,生活生产空间和生产生态空间降幅最大;生态空间则处于增长趋势。低等级区域集中在乡镇建成区内,尤以主城区、龙湖镇、航空港经济区较为集中;较高和高等级区域集中在始祖山周边和双洎河、杨庄水库等水域。③"三生"用地转变导致区域生态系统服务价值持续降低,归因于生活生产空间对其他空间的侵占,尤其是居住地和工交用地对旱地的大面积侵占。④在快速城镇化地区优先控制区域生态底线和优化城镇人居环境内部生态功能,对于开展区域"三生"空间优化具有重要指导意义。
An improved equivalence factor method was used to evaluate the land use transformation and its response to ecosystem service value in Xinzheng City, Henan Province. The research showed that(1) the continuous enhancement of life production function in the region is the main direction of the land transformation, with a growth rate of 41.55%, which is mainly due to the occupation of ecological space by industrial space.(2) The value of ecosystem services continues to decline, especially after 2010, and the rate of decline is significant(-35.63%). The living-production space and production-ecological space decline the largest, and the ecological space is in a growing trend. The low-level areas are in the township built-up areas, especially the main city, Longhu Town and the airport economic zone. The higher and highest-level areas are in the waters of the Shizu Mountain, Shuangyu River and Yangzhuang Reservoir.(3) The transformation of ecological-living-industrial land has led to a continuous decline in the value of ecosystem services, due to the occupation of some spaces, especially the occupation of farmland by production land.(4) Priority control of the regional ecological bottom line and optimization of the internal ecological functions of the urban habitat environment in the rapid urbanization area have important guiding significance for the development of regional ecological –living-industrial space optimization.
