摘  要：
以神东矿区宝勒高水库保护区为研究区域,通过野外调查和统计分析,对不同规格、不同坡位沙柳沙障内植被恢复情况、沙障破损情况、植被生长与沙障关系进行了详细调查,以研究影响沙柳沙障植被恢复的几个主要因子。结果表明:2 m×2 m规格的沙柳沙障最利于植被恢复;沙丘背风坡在降水较好的条件下利于先锋植物种生长,而迎风坡则表现为更利于植被的恢复及演替;背风坡沙障破损较迎风坡严重,每一障格四条边破损度依次为迎下>迎上>顺左>顺右;植被生长对沙障有明显的依附作用,障格中间不利于种子停留和植株生长,在沙丘迎风坡,顺风边植株数量和高度均略高于迎风边,而到了沙丘背风坡,迎风边植株数量和高度都高于顺风边;风力是影响迎风坡植被恢复的主要因子,坡度则是背风坡植被恢复的主要影响因子。

摘  要：
Restoration,disrepair and plant growth of the checkerboard were studied in different size and different position Salix psammophila Checkerboard,then the influencing factor of its vegetation restoration were analyzed.The results show 2 m×2 m size checkerboard is the best one for restoration;the leeward slope is good for pioneer plant growth in the plentiful rain year and the windward slope is better for the vegetation restoration and succession;the checkerboard's breakage in leeward slope is more serious than the windward slope;in each checkerboard,the breakage level of the four boundary is windward below>windward above>left before the wind>right before the wind;the plant growth has relationship with the checkerboard and the middle don't suit the seed stay and its growth;in the windward,the plant quantity and height in boundary which before the wind is higher than the windward boundary and it is opposite in the leeward slope;the mainly influencing factor in windward slope and leeward slope is the wind and gradient respectively.
