【摘要】 以位于吉兰太盐湖自然保护区的PLA沙障试验区为研究对象,选取裸沙丘为对照,从2007年到2011年,每年9-10月对PLA沙障及对照区内植被生长状况进行跟踪调查研究,结果表明:(1)与裸沙丘相比,PLA沙障内植被生长状况总体较好,但截至目前尚未形成稳定的植物群落,植被盖度年际变化较大。(2)几种规格PLA沙障相比,在促进植被生长方面,3m×3m规格最好,2m×2m规格次之,1m×1m规格最差。(3)与裸沙丘相比,设置PLA沙障后,坡位对于植被的生长状况具有一定的影响,但其规律性还需进一步的跟踪调查研究。更多还原

【Abstract】 Take the PLA sand barrier test area located in Jilantai Saline Lake natural protection area as the research object,selected bare dune as the contrast,in each September or October from 2007 to 2011,we were tracking researched the vegetation growth status of PLA sand barrier and the contrast area.Results showed that:(1) Compared with the bare dune,the PLA sand barrier have better vegetation growth condition.But so far has not yet formed a stable plant community and the interannual variability of vegetation coverage is large.(2)For different size PLA sand barrier,3m × 3m size PLA sand barrier is best in promoting the growth of vegetation.2m × 2m size is better and1m × 1m size is poor.(3) Compared with bare dune,after set the PLA sand barrier,slope position has certain effect on the vegetation growth status,but the law still needs to investigation research further.更多还原
