Temporal and Spatial Variation Trade-offs Analysis of Ecosystem Services in Ningjin County of Hebei Province
Taking Ningjin County as the research area,base on the LUCC and social and economic statistics,the value of ecosystem services in different periods were estimated,the temporal and spatial change rule of the trade-off relationship between profit and loss were analyzed.The re-sults showed that during 1995-2019,multi-functionality of ecosystem,production function and ecological function showed increased first and then decreased;the functions of climate regulation,nutrient fixation and gas regulation were showing an increasing trend;the water conservation function had significantly decreased;the pollutant containment function continued to decrease.The loss of ecosystem services caused by the re-duction of cultivated land area was the most.Multi-functionality,ecological function,water conservation function and other functions of the eco-system had changed from synergy to trade-off.
