宝鸡市几种典型水保林土壤持水能力分析

Soil Water Holding Capacity of Several Typical Water Conservation Forests in Baoji City

以3种典型水土保持林为研究对象,分析了林地土壤孔隙度和持水能力,结果表明刺槐、侧柏、油松人工林的土壤孔隙度和土壤持水能力存在显著差异,依次为油松林>侧柏林>刺槐人工林地。林地土壤持水能力与土壤孔隙状况有直接关系,但也受其他因素的综合影响,加强林地管理有利于提升人工林的水保保持功能。

Soil porosity and water holding capacity of three typical soil and water conservation forests were analyzed.The results showed that there were significant differences in soil porosity and soil water holding capacity with Robinia Pseudoacacia,Platycladus orientalis and Pinus tabulaeformis plantations,and the order of capacity was Pinus tabulaeformis>Platycladus orientalis>Robinia Pseudoacacia plantations.The soil water holding capacity of forest land is directly related to the soil pore condition,but also affected by other factors.Strengthening forest land management is conducive to improvement of water and soil conservation function of plantations.
