摘要

[目的

]

分析山西省生态系统土壤保持服务功能的空间分布格局，识别山西省土壤保持功能保护的重点区域，为生态保护红线划定和国土空间规划提供参考。[方法

]

采用修正通用水土流失方程（RUSLE）开展山西省土壤保持功能重要性评估。[结果

]

山西省土壤保持总量为6.52×10

t/a，单位面积土壤保持强度平均为416.10 t/（hm

·a）。土壤保持功能总体呈现“西北低、东南高，盆地低，丘陵和山地高”的空间分布格局，极重要区、重要区和一般重要区的面积分别占山西省国土面积的23.10%，28.33%和48.57%。[结论

]

山西省土壤保持功能极重要区主要分布在太行山、吕梁山、恒山、五台山、太岳山、中条山等组成的“多”字形山地地区，在晋西黄土丘陵沟壑区也有一定分布。

Abstract

[Objective] The spatial distribution pattern of soil conservation service function in Shanxi Province was analyzed

and the key areas that need to be protected were identified

in order to provide reference for ecological protection redline delineation and national territorial planning.[Methods] The revised universal soil and water loss equation(RUSLE) was used to analyze the importance of soil conservation function.[Results] The total amount of soil conservation was 6.52×109 t/a

and the average amount of soil conservation per unit area was 416.10 t/(hm2·a) during the study period. The spatial distribution pattern of the ecosystem's soil conservation function was low in northwest and high in southeast

as well as low in basin and high in hills and mountains. The areas of extremely important areas

important areas and general important areas accounted for 23.10%

28.33% and 48.57% of the total area of Shanxi Province

respectively.[Conclusion] The extremely important areas of soil conservation function in Shanxi Province were mainly distributed in Taihang Mountain

Luliang Mountain

Heng Mountain

Wutai Mountain

Taiyue Mountain and Zhongtiao Mountain

and it was also widely distributed in loess hill area of western Shanxi Province.
