摘要:
对退耕还林地上种植的3年生苦丁茶水土保持功能和经济效益进行了分析。结果表明：苦丁茶可显著改善土壤的物理性状，降低土壤容重，增加土壤孔隙度，提高土壤渗透性能，增强土壤的蓄水保水性能，可以有效地控制土壤侵蚀。可减少73.19%的径流量，削减86.51%的泥沙量。苦丁茶年产375 kg/hm2，直接经济效益达8万元/hm2，其生态效益与经济效益均十分显著。
Abstract:
The research was made on soil and water conservation function and economic benefit of Ligustrum purpurascens planted in Sloping Land Conversion Program.The results showed that planting of Ligustrum purpurascens can improve the physical characteristics of soil,increase soil porosity and infiltration rate of soils,reduce the soil bulk density,lessen soil erosion and control water and soil loss.The runoff and sediment was decreased 73.19% and 86.51%.And annual dry Ligustrum purpurascens can reach to 375 kg/hm2.The direct economic benefit can come to 80 000 yuan/hm2.Therefore,both ecologic and economic benefits of Ligustrum purpurascens land are of great significance.
