营造台湾相思水土保持林对土壤结构和养分的影响

Effects of Planting Acacia confusa Forest for Water and SoilConservation on the Soil Structure and Nutrient

对侵蚀丘陵地营造台湾相思（治理措施）土壤肥力变化的研究，结果表明：治理后的土壤结构、水分状况得到一定程度改善，土壤营养元素容量及供应强度明显增强，表明治理后土壤肥力得到一定程度的恢复。营造台湾相思水土保持林是治理侵蚀丘陵地较好的措施之一。

Acacia confusa forest was planted on the eroded hilly land (as a harnessing measure).The results indicated that after the harnessing,the soil structure and water status were improved to a certain extent,the soil nutrient element content and supply intensity were obviously enhanced,the soil fertility was some recovered and planting A.confusa forest for water and soil conservation was a better measure to harness the eroded hilly land
