中文摘要	通过对宁夏盐池干旱退化草场植被恢复与风蚀沙化防治技术示范区内不同种植密度的柠条林土壤水分进行了定位观测,从土壤水分日变化、季节性变化、水分垂直分布等方面进行了分析.结果表明:土壤含水量主要受大气降雨及植物生长节律的影响,变化较大.0～100 cm土壤含水量的垂直分布规律为:从表层到深层土壤含水量递增.林地土壤水分随着离柠条带距离的增加显著 (P<0.05)增加.种植密度不同土壤贮水量明显不同,密度分别为3 330丛/hm2(带间距4 m),土壤水分处于亏损状态,0～100 cm土壤贮水量极显著低于对照,柠条密度为2 490丛/hm2(柠条带间距7 m)和1 665丛/hm2(柠条带间距10 m)时,土壤含水量变化不大,但0～100 cm土壤贮水量极显著高于对照.针对盐池干旱风沙区,柠条林种植适宜密度为7 m或大于7 m为宜.退化草场种植密度土壤水分干旱风沙区.
英文摘要	The research on planting density of Caragana intet-media, which’ was established as the demonstration region of vegetation restoration and desertification control degraded grasslands on soil water,was observed in drought year of Yanchi county of Ningxia. The daily variation ,the seasonal variations and vertical distribution of soil water were analyzed. The results showed:the seasonal variations of soil water content were affiected by precipitation and plant growth. Vertical changes of soil water content increased from surface soil layer to deep soil layejr in 0~ 100 cm soil layer. The soil water content of Caragana intermedia increased at 0. 05 significance level when the distance was more far from the Caragana intermedia. The soil water content was different when the planting density of Caragana intermedia was different. The soil water content of 3 330 clump/ hm2 Caragana intermedia reserved in 0~100 cm soil layer whs lower than CK. The vegetation restoration of soil water was very little between 2 490 clump/hm~2 and 3 330 clump/hm~2 Caragana intermedia. Its soil water in 0-100 cm soil layer was higher than CK at 0. 01 significance level.The planting density of Caragana intermedia should be at 2 490 clump/hm2or lower than 2 490 clump/hm~2.
