本文在试验实测资料的基础上，由实测含水量的典型分析得出：在长期连续干旱期，刺槐林地与无林对照地、以及坡位之间几乎不存在含水量差异；在生长期的雨季初期，刺槐林地比对照无林地的含水量明显小；而在生长期的主汛期，因大量接受降水，而刺槐材地能有效地增加雨水渗入土壤，故刺槐林地比对照元林地的含水量要大。同时，利用实测资料建立了小集中区土壤水分动态的计算模型。
Based on the experimental data, a typical analysis of measured water content shows that there is almost no difference in water content between long-term continuous drought period, non-forest locust and non-forest stand, and slope position. During the growing rainy season In the initial stage, the water content of Robinia pseudoacacia forest land was significantly smaller than that of the control non-woodland land. In the main flood season, Robinia pseudoacacia forest land could effectively increase the infiltration of rainwater into the soil, Big. At the same time, the calculation model of soil moisture in small concentration area was established by using the measured data.
