摘要: 对淤泥湖水生植被的天然恢复过程、群落组成、结构、功能与动态等进行了定位研究(1992~1995).该湖水生植物共有20科29属41种.4种生活型的植物种类在该湖均有分布,以沉水草本(15种)和挺水草本(13种)为多.8个分布区类型中世界广布成分16种和东亚成分10种.群落结构包括层次结构和层片结构.该彻共有8个群落类型;群落现存量3208.8g·m-2,全湖植被资源贮量为16365.2t.

Abstract: Stationals studies including the natural restoration process of aquatic vegetation, community composition, structure, dynamics and function were conducted in Lake Yunihu. 41 aquatic plants found in Lake Yunihu falls into 20 families and 29 genera. Four life-forms of plants distribute all over the lake, with emergent (15 species) and submergent (13 species) plants predominant in numbers. There are 8 distribution types consisting of 16 worldwide components and 10 East-Asian components. Strata and sguusia structures are dealt with in community structure study.8 commnunity types are classified. The standing biomass of communitites is 3268.8 g·m-2 and the total crop in the lake is 16365.2tons.
