| 摘要: 不同垦殖方式对果园生态系统的影响试验研究结果表明，降雨强度与径流量呈指数方程，水平平台开垦是山地防止径流和土壤侵蚀的有效工程措施，而顺坡开垦种果、果树间种50cm 宽禾本科牧草形成草篱带、坡面种植优质牧草平托花生可防止径流发生。果园套种豆科牧草可降低土壤容重，增加土壤孔隙度和土壤微生物种类与数量，提高土壤含水量，增加土壤有机质、全N 和速效养分含量，调节地表和土层温度，有利于果树生长。 |

| Abstract: Effects of different planting manners on the orchard ecosystem are studied and the results show that the relationship between the intensity of rainfall and run-off amount shows an exponential function．The horizontal reclaim in terrace is the effective engineering practice to prevent run-off and soil erosion in hilly land． The practices that reclaim in down-slope for planting fruit trees ，planting the grass plants in 50cm width between fruit trees to form the gras fences，growing leguminous plants such as Pinto peanut on slope surface are the comprehensive ways to run the hilly orchard．Planting leguminous forages in new developing orchard may decrease soil bulk weight，improve soil porosity and the kinds and amount of soil microorganism ，adjust the temperatures on the soil surface and within soil layer，increase soil moisture and organic matter，improve soil fertility and increase the contents of soil total N and fast-acting nutrition．These planting practices are favorable to the growth of fruit trees ． |
