摘　　要：运用模糊数学的相关方法,建立了以水稻农艺性状和经济效益为因子的模型。采取单因素评价标准化处理与权重系数赋值方法确定各技术经济指标的权重。利用对南方稻区11个水稻品种的调研数据,计算出11个水稻品种的各指标评价值。研究发现:以"黄华占"和"黄莉占"为代表的常规稻品种总体上具有比较优势。针对目前在实际的水稻育种及推广工作中重视杂交稻、轻视常规稻的现状,提出应进一步加强常规稻的推广力度、完善优质稻的收购和加工体系、扩大优良品种的规模化种植、平衡开展育种专项支持。This paper constructs the model in which agronomic characteristic and economic benefit are the factors by the method of fuzzy mathematics.Through the standard evaluation processing of single factor and weight assignment method to determine the weight coefficients of technical economic indexes.Then using the survey data of 11 varieties of rice in southern region of China,it calculates the indicator＇s evaluation values of them.The result shows as follow：the conventional rice varieties represented by ＂ Huang Huazhan＂ and ＂ Huang Lizhan＂ have comparative advantages in comprehensive evaluation value.Finally,aiming to the present situation that paying too much attention to hybrid rice and despising conventional rice,it suggests that the popularity of conventional rice should be enhanced,the acquisition and processing system of high-quality rice should be improved,the planting scale of fine varieties should be expanded,and the support of RD about breeding should be balanced.
