摘要:
本文通过26个林草植被径流小区10年和3年观洲,分析了陕北安塞黄土丘陵沟壑区不同人工林草植被蓄水减沙效益.结果表明:不同人工林草植被除生长慢的柠条幼林外,其余8个林种均较对照牧荒坡蓄水效益显著;柠条成林、刺槐成林保土减沙效益最好,2～4年生沙棘幼林,1～6年生刺槐幼林、1～6年生刺槐×紫穗槐幼林减沙效益较好;2～4年生侧柏×紫穗槐幼林有一定减沙效益;幼树生长慢的柠条幼林、沙棘×油松、沙棘×杨树幼林无减沙效益.退耕农地种植牧草,蓄水减沙效益均好于对照农耕地,以沙打旺草
Abstract:
The effet of water conservation and sediment reduction on artificial vegetation on loess hilly and gully region in north Ansai is analysised in this paper by 10 years observation from 26 runoff plots.The results showed that 8 species of artificial woodland were much better than wasted rangeland in water conservation except yang slowly growing Caragana woodland.The grown up Caragana Korshskii and Robinia Pseeudoacacia were best in sediment reduction;2-4 years old Hippophae Rhamnoids,1-6 years old Robinia Pseudoacia and 1-6 year old Robinia Pseudoacia mixed with Amorpha Fruticosa better;2-4 years old Biota Orientalis and Amorpha Fruticosa mixed woodland had some effects on sediment reduction and slowly growing Caragana Korshinskii,Pinus Tabulaeformis mixed with Hippophae Rhamnoides,Hippophae Rhamnoides mixed with Popolus Daridiana had none.It could increase the effect of water conservation and sediment reduction by changing the slope cropland to artificial grassland,of which,the Astragalus adsurgens is best.
