施用有机肥料改善土壤物理性质，配施不明显改变pH。

Applying the organic fertilizer could improve the soil physical property , rational application could not obviously change pH.

结果表明：马尾松生长能改良土壤物理性质，特别是对0～20cm土层改良效果较为明显。

It shows that masson pine can ameliorate soil physical properties , especially to the layer 0 ~ 20 cm .

毛竹根系对土壤物理性质影响较大，0～60cm土层的总孔隙度为71.7%，林地稳渗率达8.28mm/min。

The root system of P. pubescens has a greater effect on soil physical properties . As for the soil layer of o ~ 60cm , the total porosity is 71.7 % , final infiltration ratio 8.28mm/min .

考虑到耕作层与非耕作层在土壤物理性质上的差异.用Saint-Venant方程和改进后的Green-Ampt下渗模型联立，对成层土上的畦灌非恒定流方程进行数值模拟。

Considering the difference in physical properties between different layers of soil , a mathematical model of unsteady flow in border irrigation is constructed by means of Saint-Venant model combined with the improved Green-Ampt infiltration model . The numerical solution is in good agreement with field observation .
