我国水产养殖发展潜力分析

Analysis on the development of aquaculture in China

通过历史数据,结合聚类分析方法,从我国水产品发展的时空角度,探讨内陆和海水产品养殖发展的特点。运用部分调整模型,对我国内陆和海水产品养殖业生产潜力进行剖析,并对比分析内陆水产品人工养殖与海水产品人工养殖,指出就长期边际产量而言,内陆水产品人工养殖是海水产品人工养殖的2.5倍。内陆水产品人工养殖比海水产品人工养殖前景更广阔。

In the present paper, by analyzing historical data combined with cluster analysis method, the characteristics of development of inland and marine fishery culture have been discussed from spatial-temporal angle of aquatic products development in China. Production potential of inland and marine fishery culture was analyzed by using＂ partial adjustment model, and artificial inland fishery culture was compared with artificial marine fishery culture. On the basis of this analysis it was estimated that the marginal yields of artificial inland fishery culture was 2.5 times compared to artificial marine fishcry culture. Therefore, artificial inland fishery culture had wider prospect than artificial marine fishery culture.
