摘要
以黄河三角洲为例,分析了黄河三角洲地区植被分布,选取典型的植被类型分析其最适宜生长的盐分范围及地下水位埋深与区域土壤含盐量间的关系,确定了最适宜研究区植被生长的地下水位埋深。基于地下水临界蒸发深度,并综合考虑土地利用状况、海水入侵问题最终确定了黄河三角洲的地下水生态水位埋深,对防止土壤盐碱化、保护生态环境具有重要意义。
Taking the Yellow River Delta region for an example,the vegetation distribution is analyzed.The appropriate growth salinity range and the relationship between groundwater cover depth and the regional soil salt content is analyzed by selecting the typical vegetation type.The groundwater cover depth for optimum vegetation growth is determined.Based on the groundwater critical evaporation depth,the groundwater ecologic level cover depth in the Yellow River Delta is determined with considering the land utilizat...
