陕西省永寿县常宁公社,位于泾河中游深切河曲的西岸与永寿梁之间,属黄土高原破碎塬区(图1)。该类型在秦岭以北除关中盆地外,是农业生态条件较好、生产潜力较大的地区。为此我对该社的农业生态因素作了一些动态解析,根据动态规律提出了高产稳产农田建设的途径,供黄土破碎塬区农田基本建设的参考。
Changshun County, Shaanxi Province, Yongning commune, located in the middle reaches of the Jinghe river between the West Bank and Yongshou Liang, a Loess Plateau broken plateau (Figure 1). This type is located in the north of the Qinling Mountains in addition to Guanzhong Basin, is a better agricultural ecological conditions, the potential for production of large areas. To this end, I made some dynamic analysis of the agroecological factors of the society and put forward the ways of high-yield and stable-yield farmland construction based on the dynamic law for the reference of the farmland construction in the loess plateau area.
