【摘要】 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。为丘陵如何综合治理提供有力的科学依据。更多还原

【Abstract】 According to the natural condition and the production characteristic, we established an agricultural nature productive potential analysis model and an unified model in terms of light, temperature, water and soil condition. The models indicated that the most important limit factor. which restrict agriculture nature productive potential in north foothill of the Yin Shan is the change of soil fertility caused by wind erosion. The second limit factor is the different soil moisture in different topography. In addition, the configuration structure of light, heat and water could also be limit factors. The results provide the powerful scientific basis for the comprehensive manipulation of hills更多还原
