摘要: 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。

Abstract: Evaluation of different planting modes is one of the hot spots in today’s cropping system research. In terms of western Liaoning Province’s natural characteristics and diverse planting modes, this paper evaluated six typical planting modes adopted in this region, based on experimental studies and expert questionnaire surveys and by the method of gray relational analysis. The results showed that whether under average or variable correlation of ecological indices or economic indices, the planting mode of Nanguo pear with pumpkin was most closely related to reforence pattern, with the correlation being 0.867, 0.920, and 0.841, followed by the planting mode of Nanguo pear with peanut, the correlation being 0.848, 0.901, and 0.821, indicating that the planting modes of Nanguo pear with pumpkin or peanut had the best ecological and economic benefits, being the optimal planting modes in western Liaoning Province. The planting mode of corn intercropped with soybean was less related to referential pattern, with the ecological and economic benefits being comparatively worse. This study would provide a theoretical support in protecting the ecological environment, developing the multi-dimensional agriculture, and enhancing the sustainable development of regional society and economy in western Liaoning Province.
