摘　　要：通过野外踏查和样带、样方调查法,利用物种多样性指数和群落相似性指数,对派河流域滨岸带不同植物群落结构及其与水质联系进行分析比较,从而构建出适合派河治污的缓冲带模型。结果表明:该流域滨岸带植物物种组成共有92科204属254种,其中主要生活型植物为草本植物。整条流域、不同河段和不同岸坡高度的植物群落的多样性指数大小存在差异,且数值普遍较低。由于所处生境差异和人为因素的影响,不同河段和不同坡面高度的群落相似性均不同。滨岸缓冲带的宽度及其植物搭配的复杂程度对于河道水质的改善具有重要作用。综上可知,派河流域滨水带植物组成较为丰富,但各群落物种丰富度偏低,不同空间位置的群落异质性较大,滨岸缓冲带模型可构建为在不同岸坡高度错落分布一定宽度的乔灌草搭配模型来改善派河水质。Through the field survey,the sample line and sample survey methods,the species diversity index and the community similarity index were used to analyze and compare the different plant communities.And their relationship with water quality were analyzed to build a buffer strip model suitable for river pollution control.The results showed that:there were 92 families,204 genera and 254 species in the plant communities in riparian zone of the Paihe River,among which the main living species were herbaceous plants.The diversity index of plant communities in the whole river basin,different watersheds and bank slope heights was different,and the values were generally low.Due to the habitat differences and human factors,similarity of different watersheds and bank slope heights were with great difference.The width of the riparian buffer strips and the complexity of the coastal buffer zone plant played an key role in improving river water quality.In summary,the riparian zone plants in the Paihe River Basin were rich in plant composition,but the species richness of each community was low,and the heterogeneity of the communities in different spatial locations was large.The riparian buffer strips model could construct a certain width distributing of the arbors,shrubs and herbs in different bank slope heights to improve the water quality of the Paihe River.
