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.
