| 摘 要： | 民勤是我国重点防沙治沙的地区,为了治理沙害从新疆引入梭梭种营造了大面积的人工梭梭林,由于环境的变迁,人工梭梭林退化严重.通过野外调查人工和天然梭梭林更新苗的分布现状,结果表明:人工梭梭林开始出现自然更新,其更新苗的聚集性特征明显,幼苗的生长与存活受到了抑制,保苗率极低；比较天然梭梭林更新幼苗的空间分布特征,人工梭梭林幼...

| Abstract: | Minqin is the focus of anti-desertification areas in China.In order to control sand harm,Haloxylon am-modendron were introduced from Xinjiang,and a large area of artificial Haloxylon ammodendron forests was construct-ed.Because of the environmental changes,the artificial Haloxylon ammodendron was seriously degenerated.Based on field investigation,the regeneration of artificial and natural Haloxylon ammodendron forests was surveyed.The results showed that natural regeneration of artificial Haloxylon ammodend... |
