| 摘 要： | 对半干旱地区疏林式草牧场防护林土壤改良效应进行了研究。与无防护林庇护的草场相比，疏林式草牧场防护林具有明显的土壤改良效应。可以调节地表极温、地中温度和地表温度，提高土壤的含水率，降低土壤密度，改善土壤孔隙度、透气度和土壤水分等物理特性，可提高庇护草场土壤的有机质、全氮、速效磷和速效钾等差分的含量，进而可改善土壤的物理性质及化学性质，为防护林内牧草的生长提供良好的土壤环境。 |

| Abstract: | In the paper. soil amelioration effects of protective plantation of sparse woods on grassland and pastureland in the semi-arid windy and sandy area were studied. Compared with the open area. protective plantation of sparse woods has obvious soil amelioration effects. It can adjust extreme ground temperature, ground temperature. and underground temperature. It can increase soil moisture content and reduce soil gravity. It can also improve soil opening capacit.y, ventilating capacity, and physical properties of soil water. Furthermore. it can increase soil nutrient content. such as organic substance. total nitrogen. quickacting phosphorus. and quick-acing potassium, etc. In one word. protective plantation of sparse woods can ameliorate physical character and chemical character of soil in sparse woods. ac provide with better condition of soil for herbage. |
