    摘要:

    通过对宁南山区采取不同恢复措施的土壤水分、理化性质及酶活性的研究结果表明:土壤平均含水量最高的是农田18.61%,其次为林地16.73%、人工草地9.95%,最小的为天然草地9.20%;土壤总孔隙度、土壤碱解氮排列顺序为林地〉农田〉人工草地〉天然草地;土壤毛管孔隙度、土壤速效磷平均含量排列顺序为人工草地〉林地〉农田〉天然草地;土壤有机质平均含量为灌木林地〉农田〉天然草地〉人工草地;土壤速效钾的平均含量为天然草地〉农田〉人工草地〉灌木林地。土壤尿酶含量为人工草地〉天然草地=农田〉林地;土壤蔗糖酶、多酚氧化酶的含量为人工草地〉天然草地〉林地;过氧化氢氧化酶的含量为人工草地〉天然草地=农田〉林地。

    Abstract:

    Studying the soil water,physical and chemical properties as well as enzyme activity of different ecological restoration measures in Ningnan hilly area,the results showed that:the soil average moisture content in the farmland was the highest(18.61%),next the forest land was 16.73%,the artificial lawn was 9.95%,the natural pasture was the smallest(9.20%);the order of soil total porosity,soil hydrolysis N was forest land> farmland >artificial lawn >natural pasture;the order of the average content of soil capillary tube porosity,soil fast-acting phosphorus is: artificial lawn> forest land >farmland> natural pasture;the average content of the soil organic matter is the bush forest land > farmland > natural pasture > artificial lawn;the average content of the soil fast-acting potassium is the natural pasture > farmland > artificial lawn >bush forest land;the soil urine enzyme content is the artificial lawn > natural pasture = farmland > forest land;the soil sucrase,the polyphenol oxidase content is the artificial lawn > natural pasture >forest land;the hydrogen peroxide oxidase content is the artificial lawn > natural pasture = farmland > forest land.
