三江源地区一年生禾豆混播人工草地最佳混播比例的综合评价研究

A comprehensive study evaluating the optimal mixing ratio of annual gram-bean mixed artificial grass in the Sanjiangyuan area

摘要:

【目的】探究青海省三江源地区建立人工草地混播体系最佳综合评价模式。【方法】采用 3 种不同综合评价方法筛选适宜在三江源地区建植的禾豆混播组合及比例。【结果】3 种评价方法，AHP 层次分析法评价方法中最优混播组合及比例为燕麦+箭筈豌豆（70∶30），隶属函数评价方法中最优混播组合及比例为燕麦+箭筈豌豆（60∶40），灰色关联度评价方法中最优混播组合及比例为燕麦+箭筈豌豆（70∶30）。【结论】结合试验地区海拔条件等因素，在高寒地区优先推荐灰色关联度综合评价方法，燕麦+箭筈豌豆（70∶30）混播模式为一年生禾豆混播最佳混播组合及比例。

Abstract:

【Objective】 In order to investigate the optimal comprehensive evaluation model for establishing an artificial grass mixed seeding system in the Sanjiangyuan area of Qinghai Province.【Method】 This paper employed three different comprehensive evaluation methods to screen suitable gram‐bean mixed seeding combinations and proportions for planting in the Sanjiangyuan area.【Result】 The test results revealed that，among the three evaluation methods chosen，the AHP hierarchical analysis method identified the ideal mixed sowing combination and ratio as Avena sativa + Vicia sativa（70∶30），the affiliation function evaluation method identified it as Avena sativa + Vicia sativa （60∶40），and the gray correlation evaluation method determined it as Avena sativa + Vicia sativa（70∶30）. 【Conclusion】 The best combined combination and ratio of Avena sativa + Vicia sativa（70∶30） is proposed for the alpine region，based on the the integrated gray correlation evaluation approach，considering the altitude conditions of the test area and other parameters.
