不同种植模式评价是当今种植制度研究中的热点之一,针对辽西地区自然特点和种植模式混杂多样的现状,在多年试验研究和专家问卷调查的基础上,采用灰色关联度分析方法对辽西地区6种典型种植模式进行了评价。结果表明:无论是在等权关联度下还是在侧重生态环境指标或经济指标的变权重下,南果梨+南瓜种植模式与参考模式的关联度均为最大,分别为0.867、0.920和0.841,南果梨+花生种植模式次之,说明南果梨+南瓜‖花生的林粮间作模式的生态和经济效益最好,是辽西地区发展种植业的最佳模式,玉米/大豆间作模式的关联度最小,分别为0.848、0.901和0.821,这种模式的生态和经济效益最差。该研究结果对保护辽西地区生态环境,发展多熟立体农业,推动该区域的社会经济与环境的协调发展提供了理论依据。
According to many years of experimental research and expert questionnaire survey, aiming at the current situation that the natural characteristics and planting patterns in the western Liaoning are mixed and varied, this paper uses gray relational analysis The typical planting pattern was evaluated. The results showed that the correlation between Nanguo pear + pumpkin planting patterns and reference patterns was the highest at 0.867, 0.920 and 0.841, respectively, no matter under the relation of equal rights or under the weight of changing ecological environment or economic indicators. The results showed that the best ecological and economic benefit was the best ecological and economic benefit of Nanguo pear + pumpkin ‖ peanut planting and planting, the best model for planting industry in Liaoxi area, and the least correlation between maize / soybean intercropping model respectively 0.848, 0.901 and 0.821, this model has the poorest ecological and economic benefits. The results of this study provide a theoretical basis for the protection of the ecological environment in Liaoning Province, the development of multi-crop three-dimensional agriculture and the coordinated development of social economy and environment in the region.
