摘要
贵州喀斯特地区土壤侵蚀十分严重,已引起广泛关注,通过对黔中喀斯特石灰岩地区表层土壤结构性.土壤抗蚀性能和抗冲性能研究,表明乔木林对改善土壤结构有重要作用,林下植被的覆盖度对土壤结构的影响也较大。定量分析表明土壤结构性对土壤抗蚀性和抗冲性的影响较大,相关系数和回归分析达到了0.01极显著性水平。保护植被、预防石漠化已刻不容缓。
Soil erosion of karst area in Guizhou province become more severe, which has arisen broad attention. The research on the surface soil structure,soil anti-erosion and soil anti-scour in the limestone region of karst area in the middle of Guizhou province shows that arbor forest improve the soil structure and contain important function,the overlay degree of vegetation under the forest has the great influence on the soil structure. The quantitative analysis showed that soil structure is main factor influencing soil anti-erosion and soil anti-scour with both correlate coefficients and regression analysis through the significant test at level 0. 01. The protection of vegetation and preventing the stone desertification from turn already urgent.
