【摘要】 云南省环境科学研究院建设全封闭围隔工程控制蓝藻水华灾害。全封闭围隔对蓝藻的阻隔效果较好:在78.13%的时间里,风力较弱(1级和2级风)的情况下,全封闭围隔可完全阻隔蓝藻,阻挡和导流蓝藻效果显著;在93.78%的时间里(1、2、3级风),全封闭围隔可阻隔绝大多数蓝藻,其拦挡和导流效果仍然较好;但在极端恶劣天气,如大风浪(4级风以上)的情况下围隔受风生流影响出现下沉现象,其阻隔和导流蓝藻的功能部分丧失。更多还原

【Abstract】 The enclosed enclosure was experimented to control the water bloom in Dianchi Lake. The effect of the enclosure was excellent in general. The water bloom was completely isolated by the enclosure when wind force scale was measured in 1or 2 level that occurrence frequency was about 78. 13%. The bloom was mostly isolated when wind force scale were 1,2 and 3 levels in the occurrence frequency of 93. 78%. However,the enclosure partially lost its function in the extremely bad weather,especially in or above 4 level wind.更多还原
