摘要
为建立淡水池塘养殖监测体系,分析典型流域池塘养殖主产区域的差异与变化,在黑龙江、长江、珠江、黄河等流域设置40个池塘养殖监测站点,选取养殖环境、养殖结构和养殖生产等3大类要素各14个、11个、10个计35个监测指标,通过监测站点采集指标数据。在不同流域的池塘养殖模式中,共有34个站点完成监测,获得监测指标2620个,其中,养殖环境要素指标1844个,养殖结构要素指标423个,养殖生产要素指标353个。每个流域选取主要监测站点作为分析对象,用3个养殖环境监测指标、3个养殖结构监测指标、4个养殖生产监测指标作为代表性分析指标,比较不同流域之间和同一流域不同监测站点之间的差异。结果显示:各流域代表性监测指标表现出一定的差异,具体差异依据自然环境、养殖技术和各种生产投入而有所不同。各监测指标比较结果表明,化学需氧量、总氮含量、产量、经济效益、投入品-饲料、投入品-渔药等6个指标能够更直接展现各个监测站点之间的异同;建立的淡水池塘养殖监测指标体系能够有效反映出典型流域在养殖环境、结构和生产等要素之间存在的差异性,可以作为今后开展淡水池塘养殖基础性、长期性监测的候选指标。
Forty monitoring stations were set up in the Heilongjiang River,Yangtze River,Pearl River and Yellow River basins to establish a freshwater pond culture monitoring system and the differences and variations in pond culture in the main aquaculture production areas in typical river basin were analyzed by 35 monitoring indicators of three major categories of factors,including 11 indicators of culture structure,14 of culture environment and 10 of culture production.A total of 2,620 monitoring indicators,including 1,844 indicators of culture environment,423 indicators of culture structure and 353 indicators of culture production factors were obtained from 34 monitoring stations of pond culture modes in different river basin according to collect indicator data on each monitoring station.The major monitoring stations in each river basin had been chosen as analyzed objective.As the representative monitoring indicators,3 indicators of culture environment,4 indicators of structure and 4 indicators production were selected to perform comparative analysis of the difference among different river basins and the diverse monitoring stations in the same river basin.The results showed that there were differences in representative monitoring analyzed indicators at each river basin,which were varied according to the natural environment,culture technology and production inputs.In comparison of every monitoring indicator,the 6 indicators including chemical oxygen demand,total nitrogen level,yield,economic benefit,input feed and input fishery medicine directly demonstrated the similarities and differences among monitoring stations.The findings verified that the fresher pond culture monitoring indicator system constructed here effectively reflected the existing differences among the factors of culture structure,environment and production in typical river basins,therefore,the indicators are determined as candidate indicators to carry out the fundamental and long-term monitoring for freshwater pond culture in future.
