英文文献：Bio-Economic Development Of Floodplains: Farming Versus Fishing In Bangladesh-洪泛平原的生物经济发展:孟加拉国的农业与渔业

英文文献摘要：
This paper explores the linkages of environment and economic development in the floodplain of large rivers. There is considerable evidence that even the most vital floodplains in the world are not being managed efficiently and both economic and ecological factors need to be considered for effective management. Floodplain management policies in Bangladesh emphasize structural changes to enhance agricultural production. However, these structural changes reduce fisheries production, where the fishery is an important natural resource sector and a source of subsistence for the rural poor. We develop a model where net returns to agriculture and fisheries are jointly maximized taking into account the effect of flooding depth and timing on production. Results for a region in Bangladesh show that optimal production in a natural floodplain yields higher net returns compared to a floodplain modified by flood control structures. This finding has important implications for management policies -- neglecting the bio-economic relationship between fisheries and land use may significantly affect the long-run economic role of a river floodplain, particularly in a poor country.
本文探讨了大江河漫滩环境与经济发展的关系。有相当多的证据表明，即使是世界上最重要的冲积平原也没有得到有效的管理，有效的管理需要考虑到经济和生态因素。孟加拉国的冲积平原管理政策强调结构改革，以提高农业生产。但是，这些结构变化减少了渔业生产，因为渔业是一个重要的自然资源部门，是农村穷人的生计来源。考虑到洪水深度和时间对生产的影响，我们开发了一个农业和渔业的净收益共同最大化的模型。孟加拉国某地区的研究结果表明，自然洪泛平原的最佳生产产生的净收益要高于经防洪结构改造的洪泛平原。这一发现对管理政策具有重要意义——忽视渔业和土地利用之间的生物经济关系可能会显著影响河流泛滥平原的长期经济作用，特别是在穷国。
