基于生态系统服务价值理论,运用GIS技术和USLE模型定量评估不同整理类型土壤控制侵蚀价值.以邛崃市孔明乡为研究对象,结果表明,三种土地整理类型项目实施前后土壤控制侵蚀价值都有所提升,其中土地开发区增加了2.73万元,增幅为23.1%;土地复垦区增加了13.01万元,增幅达168.5%;土地整理区增加了31.11万元,增幅为17.6%.控制侵蚀价值增幅以土地复垦区为最高,土地开发整理对项目区水土保持有着积极的影响.
Based on the value theory of ecosystem services, the GIS-based and USLE models were used to quantitatively evaluate the soil erosion control values of different types of soil consolidation. The study was conducted on Kongming Township of Qionglai City. The results showed that the soil erosion control values of the three land consolidation types Of which land development zone increased by 27,300 yuan, an increase of 23.1%; land reclamation area increased by 130,100 yuan, an increase of 168.5%; land consolidation zone increased 311,100 yuan, an increase of 17.6% .Erosion control value increase Taking land reclamation area as the highest, land development and consolidation have a positive impact on water and soil conservation in the project area.
