The main contents include : water environment , marine sediment and the trend monitoring of marine life quality ; at the same time , to consolidate the monitoring of the functional zones , such as seashore bathing places , oceanic reserves , marine aquafarms ; to set up the seashell monitoring and controlling zones in the sea areas of both pingtan and yunxiao at the first time ; to carry out the statistical monitoring of polder , exploiting sea sand , spartin aallerni flora , terrestrial sewages , etc . , to carry out monitoring of the total quantity of pollutants into the offshore marine areas in the min river , the jiulong river as well as the municipal sewages of xinlin industry in xiamen and jiaocheng in ningde ; to carry out the red tide monitoring in the offshore marine areas of fujian province ; to implement time - lapse , pointing and continuous red tide monitoring of high frequency and high intensity in the sandu gulf , the min river estuary and offshore marine areas of xiamen 主要内容包括水环境、海洋沉积物和海洋生物质量的全海域环境趋势性监测，同时加强了海水浴场、海洋保护区、海水增养殖区等功能区监测；首次在平潭和云霄海域设置了贝类监控区；开展了围填海、海砂开采、互花米草、陆源排污口统计监测；并在闽江、九龙江、厦门杏林工业排污口、宁德蕉城市政排污口邻近海域开展污染物入海总量监测；在全省近岸海域开展赤潮监视监测，对三都湾、闽江口、厦门近岸海域赤潮监控区实施高频率、高密度的定时定点连续监测。
The results showed that each river flow has a tendency to gradual decrease mainly by soil and water conservation in the above four catchments . the critical year of the river flow decrease was 1974 , 1974 , 1977 and 1974 for jia - lu - he , tu - wei - he , pian - guan - he and qiu - shui - he catchments , respectively . each river flow has been divided into prophase and anaphase period according to the critical year 结果表明：水土流失综合治理是引起径流量减少的主要原因之一；从上世纪七十年代以来，四条流域的年径流量均出现逐年减少的趋势；在研究时段内，佳芦河、偏关河、秃尾河和湫水河径流量发生趋势性减少的临界年份分别为1974年、 1974年、 1977年和1974年。
