山西晋中地区属半湿润偏旱区。其气候特点是,生长季节短,降水量少,季节分配不均,年际间变化大,干旱缺水是农业生产的主要限制因素之一;丘陵地区坡耕地水土流失严重,风沙地风蚀威胁大,如何通过合理的土壤耕作及各种保水保土措施,蓄保降水,减少土壤水蒸发和水土流失,
Shanxi Jinzhong area is a semi-humid dry area. Its climatic characteristics are: short growing season, small amount of precipitation, uneven seasonal distribution and large annual variation. Drought and water scarcity are one of the main limiting factors in agricultural production. Soil erosion on sloping farmland in the hilly area is serious, and the risk of wind erosion is large , How to conserve precipitation and reduce soil water evaporation and water and soil erosion through rational soil cultivation and various water and soil conservation measures,
