中文摘要	内蒙古阴山北麓后山地区处在中国北方农牧交错区。这一地区自然条件恶劣，水土流失、风蚀沙化严重，生态环境极其脆弱，急需治理。本区地形以缓坡丘陵为主，坡耕地占很大比重，因此加强坡耕地的治理显得十分必要。根据研究区的自然条件及生产特征，建立了光、温、水和土壤条件对丘陵坡耕地的农业自然生产潜力的分析模型和综合模型，表明制约阴山北麓缓坡丘陵坡耕地农业自然生产潜力的主要限制因子是风蚀引起的土壤肥力的变化，其次是地势造成的土壤水分的不同，再次是光、热、水配制结构不平衡。通过农业自然生产潜力的分析，得出丘陵顶部的农业自然生产潜力最低。其次是北坡，最高是南坡，因此，要加大对坡顶和北坡的综合治理力度。
英文摘要	The gentle slope hills of ecotone between agriculture and animal husbandry lie in the north of China with very serious natural condition, characterized by loss of top surface soil, wind erosion, degradation and serious desertification. Because of this, the environment needs to be recovered. The agricultural production is low, which due to degradation of local soil, so it is urgently necessary to restore environment. Because most areas in the ecotone are gentle slope hills, and the slope plowland accounts for a large proportion, so it＇s very important to manage eco-environment in the gentle slope hills. According to the natural condition and the production characteristic, we established an agricultural nature productive potential analysis model and a unified model in terms of light, temperature, water and soil condition. The models indicated that the most important constraint factor, restricting productive potential in the north foothill of the Yin shan was the down of soil fertility caused by wind erosion. The second constraint factor was the different soil moisture at different topography. In addition, the configuration structure of light, heat and water may also be the factors. The results showed nature productive potentiality of farming agriculture content was highest in the south slopes, the lowest on the top of the gentle slopes and in the north slopes in the gentle slopes of degree. So it＇s very important to manage eco-environment on the top of the gentle slopes and the north slopes.
