摘要
为了检验区域农业市场化发展对于水土流失的影响,以江西省为例,结合对水土流失驱动力因素的分析,构建了区域水土流失驱动力模型,并据此分析了1988～2000年区域农业市场化发展对水土流失治理的贡献。结果表明,农业市场化程度的提高,有利于提高水土流失治理的效率。1988～2000年,江西省的农业市场化水平提高了15.2%,由此通过农户行为作用,水土流失面积减少61.4471万hm2,相当于2000年水土流失面积的18.36%。因此,区域农业市场化程度每提高1%,水土流失面积将减少40.43万hm\+2。最后,就区域农业市场化进程中如何进一步推进水土流失治理,提高水土保持效果,提出了相关建议。
The authors take Jiangxi Province as an example to test the response of soil and water losses on regional agricultural market liberalization. Based on the analysis of study area, the paper establishes a model including the driving factors of soil and water losses. This paper analyzes the contribution of regional agricultural market liberalization from 1988～2000 to the decreasing of soil and water losses. The research result shows that, accompanied with local agricultural market liberalization increasing 15.2% from 1988 to 2000, the area of soil and water losses decreases 61.447 1×10~4 hm^2, which is 18.36% of total area of soil and water losses in 2000. If local agricultural market liberalization increases 1%, the area of water and soil losses will decrease 4.043×10~4 hm^2. So regional agricultural market liberalization benefits from the decreasing of soil and water losses. Finally, ameliorative measures for the soil-water losses are given.
