通过对北方农牧交错带不同地区不同土地利用方式下的不同深度土壤水分含量进行分析,得出以下几点初步结论:土壤水分含量的空间差异显著,各采样点不同土地利用方式下土壤水分含量相差较大,但在具体表现上不尽相同;同一地区,不同土地利用方式下的土壤含水量变化明显;同一地区,同一土地利用方式下,不同深度的土壤含水量变化幅度较小,但仍体现出上层偏小,下层偏大的特点。降水、蒸发、土地利用方式、土壤质地、海拔高度、坡度、人类活动等因素是影响不同采样点土壤含水量变化的主要原因。
Based on the analysis of the soil moisture under different land use patterns in different regions of the ecotone between agriculture and animal husbandry in northern China, the following conclusions are drawn: the spatial differences of soil water content are significant; the soil moisture content under different land use patterns However, in the same area and under different land use patterns, the soil water content changed obviously. Under the same land use and the same land use pattern, the soil moisture content at different depths had less change, Reflects the upper small, the lower the larger features. Factors such as precipitation, evaporation, land use pattern, soil texture, altitude, slope, and human activities are the main factors affecting soil moisture content at different sampling points.
