兰州农业可持续发展的主要障碍因素分析——兼论农业多功能性

Analysis on the Main Barriers of Sustainable Development of Agriculture in Lanzhou——And Discussion to the Multi-functionality of Agriculture

农业可持续发展是一种建立在生态、经济、社会效益基础上的农业发展模式,其与农业多功能性有着密切的联系:农业多功能的实现依赖于可持续农业的技术体系和政策体系支撑,而可持续农业的实施最终以实现农业的生产、经济、环境、社会等功能的协调发展为目标。可见,农业可持续发展是实现农业多功能性的条件,农业多功能性是农业可持续发展的目标。因此,认清农业可持续发展的主要障碍因素具有极其重要的意义。文章从农业多功能性的视角出发,结合兰州市农业发展的实际,构建了兰州市农业可持续发展的障碍因素指标体系,并运用主成分分析法找出了影响兰州市农业可持续发展的主要障碍因素为:农村人均农业收入贡献率、人均园林绿地面积、绿地面积率、农业劳动力占农村劳动力比重、耕地有效灌溉率和农村恩格尔系数。

Sustainable development of agriculture is the agriculture development pattern that is based on ecology,economic and society,and it is closely connected with the multi-functionality of agriculture： Realizing the multi-functionality of agriculture is dependent on the support of technology system and policy system of sustainable agriculture,and the implementation of sustainable agriculture finally aims at realizing the coordinated development of production,economic,environment,society of agriculture and its other functions.It is thus obvious that sustainable development of agriculture is the requirement of realizing the multi-functionality of agriculture,and the multi-functionality of agriculture is the target of sustainable development of agriculture.Therefore,it is extremely important to get a clear understanding of the main barriers of sustainable development of agriculture.The article comes from the perspective of multi-functionality of agriculture,and combines the reality of Lanzhou city＇s agricultural development,and establishes the index system of barriers about sustainable development of agriculture in Lanzhou,and uses the principal component analysis to find out the main barriers which affect sustainable development of agriculture in Lanzhou city： the contribution rate of per capita agricultural income in rural area,per capita gardens and green area,green area rate,the proportion of agricultural labor in rural labor force,the effective irrigated rate of farmland and the Engel coefficient of rural area.
