河南省是我国第一粮食生产大省,粮食总产量占我国总产量的1/10,全省耕地总面积720.22万hm2,其中豫西南坡耕地总面积68.88万hm2,占全省耕地面积的9.56%,占全省坡耕地总面积的87.23%,坡耕地是耕地的重要组成部分,坡耕地在发挥经济社会效益的同时,其产生的生态问题不容忽视,这势必制约山区经济社会的持续发展。该课题研究,摸清了河南省坡耕地数量及分布,针对坡耕地治理过程中存在问题提出了科学合理的建议,从推广效果看,该课题研究成果的应用使坡耕地水土流失得抑制,生态环境得到明显改善,取得了生态环境、经济和社会效益等各方面良好效果,实现了水土保持工程的良性循环。
Henan Province is the largest grain production province in China with total grain output accounting for 1/10 of China’s total output. The total area of cultivated land in the province is 7,202,200 hm2, of which 688,800 hm2 is the cultivated land on the south slope of western Henan, accounting for 9.56 %, Accounting for 87.23% of the total area of sloping arable land in the whole province. Sloping arable land is an important component of arable land. While giving play to economic and social benefits, sloping arable land can not be ignored because of its ecological problems, which will inevitably restrict the sustainable development of economy and society in mountainous areas. The research of this subject has made clear the quantity and distribution of sloping arable land in Henan Province and put forward scientific and reasonable suggestions for the existing problems in the sloping arable land management. According to the promotion effect, the application of the research results can restrain soil and water loss in sloping arable land, The environment has been significantly improved, and achieved good results in ecological environment, economy and social benefits, and achieved a virtuous circle of soil and water conservation projects.
