摘要

研究了宁夏河东沙地农牧交错区不同放牧方式对土壤环境的影响。结果表明

不同放牧方式下的土壤含水量以6区轮牧的较高

自由放牧和封育地的土壤含水量较低

且不同放牧方式和封育地的土壤含水量随季节降雨量的变化呈-致性;封育、6区轮牧、4区轮牧和2区轮牧地土壤容重方别比自由放牧地的土壤容重下降了6%

7.77%

1.96%

1.43%;封育、6区轮牧、4区轮牧和2区轮牧地土壤总孔隙度分别比自由放牧的增加了7.38%

4.67%

3.79%

4.72%;土壤有机质、全氮、全磷、全钾的变化以自由放牧较高

不同放牧方式之间的差异不显著。土壤速效钾以6区轮牧地较高

自由放牧地较低。

Abstract

The study was conducted for different grazing systems in the ecotone of grassland and farmland in Ningxia sandy lands.Results indicated that soil moist ure was higher in the 6th rotational grazing area and lower under the conditions of continuous grazing and enclosing.The varieties of it with seasons and rainfall amount under different grazing systems had the same trends.Soil bulk densities under enclosing and u nder 6

and 2 areas rotational grazing were 6%

7.77%

1.96%

and 1.43% lower than that of continuous graz- ing

respectively

and soil porosities

7.38%

4.67%

3.79%

and 4.72%

respectively.The contents of soil organic matter

total nit rogen

total phosphorus

and total potassium presented their maximums under free grazing

but the differences among the grazing systems tested were not notable.It was also showed t hat soil rapidly available potassium u nder the 6 areas rotational grazing was higher

and under continuous grazing was lower than the others.
