黄前库区经济林土壤水文效益研究
- Title:
- Study on Soil Hydraulic Effect of Economic Forest in Huangqian Reservoir Area
- 分类号:
- S715
- 摘要:
- 以刺槐林和自然灌丛为对照，研究了黄前库区流域主要经济林类型土壤的水文生态效益。分析了不同类型土壤的物理性状、持水性能、降雨后土壤中水分的变化动态及土壤连续持水的能力等指标，总体评价库区经济林土壤的水文生态效益介于刺槐林和自然灌丛之间，说明库区植被的建设中，在避免自然植被破坏的前提下，可以将灌丛改造成为经济林，以增加经济产出。
- Abstract:
- Based on locust forest and natural shrubs,the hydraulic ecologic effect of soil of main economic forest types was dealt with.It analyzes physical characteristic,water retention performance,change of soil water content after rain,soil ability of continually conserving water and other indicators,in general the hydraulic ecologic effect of soil of main economic forest types is between that of locust forest and natural shrubs.This accounts for that during building vegetation in reservoir area,under condition of avoiding the damage of natural vegetation,shrubs can be rebuild into economic forest to enhance economic production.
