摘要
根据农业自然资源特点、经济发展水平和生态环境状况,建立了区域农业结构类型的划分方法,把区域农业结构划分为8种类型。运用这一划分方法,对浏阳市农业资源、经济与生态结构类型进行了划分,结果表明,浏阳属于农业自然资源相对短缺、经济相对发达和生态环境状况相对较差的农业结构类型。在此基础上,用定位分析方法分析了浏阳市区位、资源位、经济位和生态位特点,对15种农业生态系统模式的效益状况进行了对比分析。根据农业发展现状,针对资源利用、产业发展及生态环境方面存在的问题,提出了实现农业可持续发展的技术选择:劳动密集型技术、品种资源改良与优良农业生物资源的引进、农产品加工及深加工技术、无公害、绿色和有机食品开发利用技术、旅游资源开发利用技术及废弃物资源化利用技术。
A classification method of regional agricultural structure types was established accordcoring to the characteristics of agricultural natural resources,the developmental level of agricultural economy and the conditions of agricultural eco-environment.The regional agricultural structure was classified into 8 types.Classification methods are used to study the agricultural resources,economy and ecological structure types of Liuyang County.The results indicate that Liu-yang agricultural structure belongs to the type of relatively short of natural resources,relatively developed in agricultural economy and relatively worse in environmental conditions.Locational analysis methods are used to study the characteristics of locatio of agriculture,location of resources,location of economics and location of eco-environment in Liuyang County.Comparative analyses are made of the benefit situation of 15 agroecosystem models.In light of the situation of agricultural development,and the existing problems in resources utilization,industrial development and eco-environment,the technical countermeasures are put forward for the realization of agricultural sustainable development:labor-intemsive technology,the improvement of breed resources and introduction of good quality agro-biological resources,processing and deepprocessing technologies of agricultural products,development and utilization of harmless,green,organic food and tourism resources,as well as resourceful utilization of wastes.
