摘　　要：[目的]校园绿地土壤是校园生态系统的重要组成部分，对校园的可持续发展具有非常重要的意义。[方法]采集咸阳职业技术学院主要绿地表层（0～20cm）土壤，分析土壤的pH、容重、孔隙度及土壤有机质、N、P、K有效养分含量，以摸清校园内园林绿地土壤的肥力状况。[结果]校园公共绿地和专用绿地表层土壤容重为1．10～1．33g／cm-3，土壤孔隙度49．8％～58．4％，通气孔度〉10％，土壤pH接近当地自然土壤；附属绿地和道路绿地土壤容重为1．38～1．59．g／cm-3，土壤总孔隙度39．4％～47．9％，通气孔度〈10％，土壤pH大于当地自然土壤，不利于植物生长。土壤有机质含量变幅为6，4～12．7mg／kg，平均9．7mg／kg，处于低水平；碱解氮含量变幅为10．4～31．5mg／kg，平均18．2mg／kg，处于低水平；速效磷含量变幅为6．4～14．9mg／kg，平均为9．4mg／kg，处于中低水平；土壤速效钾含量变幅为110．3～270．8mg／kg，平均138．9mg／kg，处于中高水平。总体上看，咸阳职业技术学院绿地表层土壤主要问题是有机质和土壤氮素缺乏．附属绿地和道路绿地土壤容重大．土壤pH偏高。[结论]时校园绿地进行培肥．并且加强校园绿地土壤科肇管理。[Objective] Campus green space was an important part of campus ecological system. Soil was very important for the sustainable development of the campus. [Method] Main green land surface soil （0 -20 cm） in Xianyang Vocational and Technical College was acquired. Soil pH and bulk density, porosity and soil organic matter, N, P, K nutrient effective content were analyzed to find out the campus garden green land soil fertility conditions. [ Result] Bulk density of the campus public green space and special surface soil was 1.10 - 1.33 g/m3 , soil porosity of 49.8% - 58.4% , vent 〉 10% , and soil pH was close to the local natural soil. Bulk density of affiliated green space and road soil was 1.38 -1.59 g./m3, soil total porosity of 39.4% -47.9% , vent degree of 〈 10% , and soil pH greater than local natural soil, which wasn＇ t conducive to the growth of plants. Soil organic matter content was 6.4 - 12.7 mg/kg, and an average was 9.7 mg/kg, at a lower lev- el. Alkaline hydrolysis nitrogen content was 10.4 -31.5 mg/kg,and an average was 18.2 mg/kg, at a lower level. Available P content was 6.4 - 14.9 mg/kg, with an average of 9.4 mg/kg, in the middle and lower level. Soil available potassium content was 110.3 - 270.8 mg/kg, and an average was 138.9 mg/kg, at high levels. Overall, main problem of green land surface soil in Xianyang Vocational and Technical College was the lack of organic matter and soil nitrogen, attached green space and road soil capacity was big, and soil pH was on the high side. [ Conclusion ] Fertilizer was aoolied on the camous green soace, and the scientific management of the eamous green land was strengthened.
