中文摘要 | 根据生态交错带变化对周围环境变化具有一定指示作用的原理,利用游动分割窗技术对宁夏盐池四儿滩湿地交错带进行判定,并结合样方植被调查、生物多样性指数、降雨量等因素分析了交错带变化情况。结果表明,游动分割窗技术适用于四儿滩湿地交错带判定,适宜窗口宽度为8个样方;20062013年的交错带判定结果发现,2007年湿地宽度最大,距湿地中心距离最远,健康状况最好。之后几年各项指数呈逐年下降趋势,湿地健康状况逐年变差,其变差的原因是2008年高铁建设截断了湿地上游水源补给。因此,在注重经济发展的同时,要尽量少破坏地表径流系统,以利于湿地长远发展。研究表明,在西北半干旱区湿地健康评价和退化研究中,通过交错带的变化来反映整个湿地生态系统健康状况是一种可行的思路和方法。 |
英文摘要 | By the theory that change of interlaced zone can indicate change of its environment,the moving split-window technique was applied to the judgment of interlaced zone located in Siertan wetland,Yanchi County,Ningxia Hui Autonomous Region to confirm the causes of wetland changes.Besides,certain indexes like vegetation survey,biodiversity index and rainfall were also used for the analysis of changes of interlaced zone.The technique was suitable for judging the interlaced zone boundary of the Siertan wetland and the relative appropriate window width was found to be 8 quadrats.Meanwhile,the judgement results for the interlaced zone in the Siertan wetland showed that the wetland had the largest interlaced zone width,which was far away from the center of wetland under better conditions in 2007.However,all the indexes decreased with the increase of time from 2008 to 2013,and the conditions of wetland became worst gradually.It was the construction of railway in 2008 that truncated stream water supply,which led to the shrunk of the wetland. Therefore,it is beneficial to protect surface runoff system in developing economy so as to prompt the permanent development of wetland.It can also provide new solutions and ideas to find and solve protection and improvement problems of wetlands in semi-arid region. |
