摘要
本文在介绍我国土壤侵蚀概况的基础上,通过回顾相关文献综合影响土壤侵蚀的各种因素,利用省级数据探索了农业生产活动对土壤侵蚀的影响。研究发现,森林覆盖率、作物复种指数以及单位劳动投入等因素对土壤侵蚀作用显著。文章提出在扩大农业公共投资的背景下,应该特别关注农业生产活动本身对环境可能造成的负面影响。
Based on the reviews of the status of soil erosion and literatures on erosion relevant influence factors in China,this paper explores the impact of agricuhural production activates on the soil erosion with the provin- cial data.It is shown that forest coverage rate,crop replanting index and unit labor input have significant effects on soil erosion.One suggestion has been proposed that we should pay more attention to the possible negative effects of agricultural production on environment under the background of increasing public invest- ment in agriculture
