气候因素、土地利用变化、地形地貌条件是影响赣州市土壤保持和水源涵养功能时空分异的重要因素,针对保护空缺区域和功能退化区域,应采取生态保护和修复策略。
[Objective] The spatiotemporal pattern of soil conservation was studied and the protection vacancy areas were identified in order to provide references for regional development planning and ecological protection. [Methods] The study was conducted with data from Ganzhou City of Jiangxi Province. We used the integrated RUSLE model
the InVEST model
other ecological evaluation methods
hot spot analysis
overlay analysis
and other analysis tools combined with protection vacancy theory to analyze the space-time evolution characteristics of soil and water conservation from 2000 to 2020. We compared the existing protection areas
and identified potential priority protection areas. [Results] ① The spatial distribution of soil conservation services in Ganzhou City generally showed higher in the surrounding areas
and lower in the middle area
The most important areas were concentrated in the Luoxiao Mountains
Jiulian Mountains
Wuyi Mountains
and Yushan Mountains
with an average annual total soil conservation of 8.46×108 t. ② The spatial characteristics of the water conservation function were also generally characterized by higher in surrounding areas
and lower in middle area. The most important areas were concentrated in the upper reaches of Meijiang River basin
Pingjiang River basin
Beiling River basin
Youjiang River basin
and Taojiang River basin
as well as Wuyi Mountains to the east of Mianjiang River basin and Xiangshui River Basin. The water conservation depth averaged over many years was 213.48 mm. ③ The areas with significant soil and water conservation functions in Ganzhou City had strong spatial correlations. Compared with the existing natural reserves
the protection vacancy area was 6 155.54 hm2. There were several obvious areas with no protection around them that were located in the north of Xingguo County
the northeast of Shicheng County
the northwest and southeast of Ruijin City
and the middle of Quannan County
the southeast of Anyuan County
and the west of Xunwu County. [Conclusion] Climate factors
land use changes
and topographic and geomorphic conditions were important factors affecting the spatial and temporal differentiation of soil and water conservation functions in Ganzhou City. Ecological protection and restoration strategies should be adopted for the protection of vacant areas and functionally degraded areas.
