随着生活水平的提高,人们越来越重视生态环境。除生产功能之外的大都市区农田的生态服务和景观文化功能也日益突显。为此,根据北京市水土资源短缺的自然禀赋和改善生态环境建设“宜居城市”的要求,本文构建了以中心城区为中心的,自中心向外围的城市美化农业区、景观绿化农业区、规模农业区和山区生态农业区四个区,以及景观廊道农业带和山前林果农业带两个带;并分别根据这四区两带的自然资源特点和区位条件,确定了它们的功能定位,提出了充分考虑城市生态环境和景观美化要求的土地整理模式。基于城市水资源质量保护的原则,根据地貌部位、水资源保护区划和区位等,划分了优化培肥区、培肥区和限制培肥区,并提出了相应的农田土壤肥力水平调控模式。论文还提出了实施土地整理与农田肥力调控的政策建议。
With the improvement of living standards, people pay more and more attention to the ecological environment. In addition to the production function of the metropolitan area of ecological services and landscape culture has become increasingly prominent. Therefore, according to the natural endowment of the shortage of water and soil resources in Beijing and the requirements of improving the ecological environment “livable city ”, this paper constructs the urban beautification agricultural area with the central city as the center, Area, scale agricultural area and mountain ecological agriculture zone, as well as landscape corridor agricultural zone and piedmont agroforestry zone; and according to the natural resources characteristics and location conditions of these two zones, , Put forward the mode of land consolidation that takes urban ecological environment and landscaping into full consideration. Based on the principle of urban water resources quality protection, the optimized fertilizing area, fertilizing area and limited fertilizing area were divided according to the topography, water resources protection zoning and location, and the corresponding regulation mode of soil fertility level was proposed. The paper also put forward the policy recommendations for the implementation of land consolidation and farmland fertility regulation.
