森林植被水土保持功能评价
- Title:
- Appraising the Function of Forest Vegetation on Soil and Water Conservation
- 摘要:
- 文章评价了乔层、灌层、草层、枯落物层、根层及盖度对水土保持的影响，认为矮草层和死被层是决定水土保持效益的关键。盖度的有效性与高度关系紧密，草层和死被层仍最为有效。黄土高原人工林水土保持效益不好，其主要原因是没有完好的草层和死被层。如果林分具有良好的结构，黄土高原建造植被的减沙潜势为30%以上。
- Abstract:
- This paper appraised the effect of arbor,arbuscle,herb root,litter and cover degree on soil and water conservation.We think that herb and litter is crucial importance,the relation between the effect and height of the cover is a negative correlation.the function of litter and herb is the best on soil and water conservation. At present,the function of planted forest is very poor because there is not good herb and litter.If planted forest With high quality on the loess plateau,it will reduce sand over 30 %of the total silt discharge.
