摘    要:以位于宁夏南部黄土丘陵区的彭阳县为研究对象,通过采取“88542”整地+播种、施肥、封育等不同的调控措施,旨在寻求一种适合该区天然退化草地改良的最佳途径。结果表明:施肥和封育都可以明显地提高植被的地上生物量和盖度值、群落多样性指数,且施肥效果较明显,而在坡度大于15°的天然退化草地上,“88542”整地+播种效果尤为明显。

关 键 词:宁夏南部  地上生物量  盖度值  多样性指数  土壤水分

Abstract:The study was conducted in the Pengyang County in the southern Ningxia. “88542” site preparation +sowing, fertilizer and fencing were applied to the ground to find out an approach to restore degraded grassland. The result showed that the biomass above ground, the coverage, the plant diversity and soil water increased significantly after applying fencing and fertilizer. But on the degenerated grassland, whose slope degree was greater than 15°, “88542” site preparation +sowing was more effective.
Keywords:Ningxia  biomass  coverage  plant diversity  soil water
