摘　　要：在野外调查的基础上,采用双向指示种分析法(TWINSPAN)和除趋势对应分析法(DCA)对浊漳河湿地植被进行数量分类和排序研究。结果表明,利用聚类分析可将浊漳河湿地植物群落划分为12个群丛:马唐群丛、狼尾草+稗群丛、香蒲+慈姑群丛、香蒲群丛、矛叶荩草+大蓟群丛、旋覆花+酸模叶蓼群丛、藨草+芦苇群丛、藨草+狼尾草群丛、水莎草群丛、鬼针草+野大豆群丛、水蓼+水芹群丛、红蓼群丛;DCA排序轴第1轴(横轴)主要反映了水质和人为干扰的情况,排序轴第2轴(纵轴)主要反映了土壤水分梯度的变化情况。TWINSPAN和DCA这2种方法对样地和植物种的分类、排序结果一致,能够有效分析浊漳河湿地植物种分布的差异性;在浊漳河湿地,中生和旱生植物群落占调查总数的34.3%,说明近年来浊漳河湿地仍在发挥其作用,但干旱现象日趋严重。Based on the field investigation, this paper used two- way indicator species analysis（TWINSPAN） and detrended correspondence analysis（DCA） to do a quantitative classification and ordination of wetland vegetation in the Zhuozhang River. The results showed that the main plant species in Zhuozhang Rive wetland was classified into 12 community types by TWINSPAN. The first axis of DCA ordination expressed the water quality and human disturbance, while the second one depicted the gradients of soil humidity.The results of TWINSPAN were corresponding to those of DCA, which indicated that both the methods had good performance in handling the vegetation in Zhuozhang River wetland. Mesophyte and xerophyte population accounted for 34.3% of the survey in the Zhuozhang River basin. It showed that Zhuozhang River basin still played its role, but the phenomenon of drying trend had become increasingly serious in recent years.
