黄河三角洲滨海盐碱地绿化植物资源普查及选择研究

以我国滨海盐碱地的典型代表之一——黄河三角洲为工作点,通过对该地区绿化植物的普查和统计,根据植物生长状况及其立地条件,对该区绿化植物的耐盐碱能力进行分析研究,编制出黄河三角洲野生植物名录和黄河三角洲园林植物耐盐碱性分类表。并在此基础上,考虑到黄河三角洲的土壤、水文特点及园林绿化的制约因素,结合已经实践证明能在该区良好生长的园林植物,分析研究野生植物及其在园林绿化上的应用,联系经济效益、生态效益、社会效益,提出滨海盐碱地绿化植物资源在不同条件下的最佳选择。

Resources and Selection of Greening Plants in Coastal Alkali- saline Soil of theYellow River Delta

Based on census and statistics of the greening plants species in the Yellow River Delta,one of the typical coastal alkali-saline soils,the author analyzes the salinity and alkali tolerance of these plants and works out the plant lists of the wild plants and the classification table of their salinity and alkali tolerance according to their growth and site conditions.In addition,considering the soil,hydrological features and the restraint factors of the landscape greening,the author assays the wild plants species and their applications in landscape greening,with reference to the landscape plants species which have been proved to be well accustomed to the soil and the current greening methods in the alkali-saline soil.Eventually,the author puts forward the best choices of greening plants resources in the alkali-saline soil in different conditions after comprehensive evaluation of the economical,ecological and social benefits.
