摘要
一、水产植被的环境条件南四湖位于山东的西南部,即北纬34°27′至35°20′,东经116°34′至117°21′之间。由南阳湖、独山湖、昭阳湖和微山湖四个湖泊串连而成。各湖之间无明显界线,总面积为1126平方公里。在汛期和枯水期面积常有变化,通常水深1—2米。湖中部二级坝水利工程把其分成了不同水面高度的两个湖泊。通常情况下,上级湖水面比下级湖水面高1.5米左右。
Aerial and satellite photo with different time and scale are used, and explanatory marks of information set up in investigation of aquatic plants in Nan Si Lake. Meanwhile, explanatory contents are modified further in dealing with survey material of field investigation, resulting in higher explanatory accuracy.
According to distribution chart, the distribution area of all kinds of plants have been calculated. The standing biomass of aquatic vegetation in Nan Si Lake is estimated, with regular material and calculated area, as 2678.3 thousand'tons.
