摘　　要：程海位于云南西北部的永胜县境内。共有种子植物１４种，其中沉水植物４种。根据植物的生活型，优势种及主要种类组成，将水生植被分为北水苦荬十棒头草、石龙芮十棒头草、水田芥、扁杆麓草、扁杆麓草＋蓖齿眼子菜＋狐尾藻、蓖齿眼子菜、狐尾藻＋蓖齿限子菜、狐尾藻、狐尾藻＋苦草、苦草、菹草和轮藻等１２个群落。程海生物量约４７６６ｔ，其中沉水植物群落占９４．１％。种子植物种类贫乏，生物量低，主要是于程海为碱性、微咸水的深水湖。The Chenghai lake is located on the boundaries of yongsheng county of northwestYunnan province.There are 14 species of seed plant, amoung which there are 4 species ofsubmersedplant.Acording to the life form, dominant species and main species composition of plants,we recog-nized vegetation types as follows: 1.Veronica anagallis aquatica+Polypogon fugax community. 2.Ranunculus sceleratus+Polypogon fugax community.3.Nasturtium officinale community. 4.Potamogeton crispus community.5.Scirpus planiculmis community. 6.Scirpusplaniculmis+Myriophyllum verticillatum+Potamogeton pectinatus community.7.Potamogetonpectinatus community.8. Myriophyllum vertcillatum+Myrioplyllum certicillatum+potamogetonpectinatus community.9.Myriophyllum verticillatum community.10.Myriophyllumverticillatum+Vallisneria spiralis community.11.Vallisneria spiralis community. 12.Chara sp.com-munity.The biomass of Chenghai lake is about 4766t,among which submersed plant communitiesare 94,1%, The kinds ofseed plant is poor,biomass is low in Chenghai lake. It is because Chenghailake is the depth water lake ofalkalinity and microsalt water.
