【摘要】 对我国130余个主要湖泊的营养状况进行了分类研究。结果表明,目前处于协调营养型湖泊116个,占调查湖泊数量87.9％,占调查湖泊面积的96.0％;非协调营养型湖泊16个,占调查湖泊数量12.1％,占调查湖泊面积的4.0％;在协调营养型湖泊中,影响湖泊资源开发利用的主要障碍是富营养化问题;非协调营养型湖泊中,主要是超营养化和盐碱化问题。它们有的已经严重地影响湖区经济的发展,是我国当前亟待解决的重要环境问题之一。更多还原

【Abstract】 By studying the classification of trophic types of more than 130 China’s lakes, the results show that 117 lakes are in harmonious trophic type, 88.7% of total number of observed lakes, 96. 0% of total area, and 15 lakes in non-harmonious trophic type, 11. 3% of total number, 4. 0% of total area. The main obstacles of lake resources utilization in harmonious trophic lakes are cutrophication, and those in non-harmonious trophic lakes, are idiotrophische and saliniza-tion. The obstacles in some lakes hinder scriously the economie development of the lake re-gions. It is one of the important environmental problems in China that should solved be as soon as possible.更多还原
