- Abstract:
-
Soil and water conservation is one of the important functions of the ecosystem, which is related to the regional ecological security and water environment quality. Based on the Universal Soil Loss Equation(RUSLE), the soil and water conservation function of the ecological supporting area in Xiong'an from 2000 to 2018 was evaluated, then the function pattern and its human driving forces were analyzed. The results show that:(1)the soil and water conservation function presented a spatial pattern with the high level in the west and low level in the east, with a multi-year average value of 191.10 t/(hm2·a)in the Taihang Mountains, 119.25 t/(hm2·a)in the central hills, and 30.25 t/(hm2·a)in the eastern plain;(2)from 2000 to 2018, the function of soil and water conservation showed an increasing trend in the study area, and varied from 39.78 t/(hm2·a)to 135.62 t/(hm2·a); on the pixel scale, the area with the enhanced soil and water conservation function accounted for 63.89% of the study area, of which 28.75% passed the significance test; while the area with a degraded tendency accounted for 36.11%, of which 8.2% passed the significant test;(3)based on the analysis of typical soil and water conservation function areas in the Xiong'an New District, it was found that the human driving forces of the variety function of soil and water conservation mainly included the ecological construction, agricultural production, construction land expansion, and mining industry disturbing ecosystem stability. This study can offer the scientific basis for determining ecological protection and restoration priorities and improving the ecological environment quality in the ecological supporting area of the Xiong'an New District.
