国外城市农业研究进展及展望(5)
4.3 城市农业与城市规划的融合
城市农业发展主要是自下而上的过程,通常由个人或非政府组织而不是政府或由规划者推动,还难以成为城市规划的主流要素[70-71]。城市农业要实现持续发展,须融入所在城市规划,逐步构建从上而下的支撑机制,未来研究须加强系统动力学等复杂模型构建,建立多情景分析与空间决策工具,由相对简单的静态研究向多情景设置的动态模拟研究转变,以找到更有效的方法支撑城市农业融入城市规划。
4.4 多学科知识方法的综合应用
实践中需要大量科学研究明确城市农业合理定位,包括决策者、科学家、工程师、居民等多方主体参与,涉及农学、建筑、城市规划、工程、经济和公共卫生等学科知识的融合应用。城市农业研究带有明显的交叉学科特点[72]。未来须加强社会调查、GIS、RS、统计学等技术的结合,尤其近年来GIS和RS技术发展为研究提供了新手段,其运用的潜力值得进一步深入。
我国城市农业研究起步较晚,目前研究框架与方法多是传统农区农业研究的延续,没有将城市农业当做单独的领域来对待,在概念、内涵、系统边界、量化研究等方面较为薄弱,研究视角偏窄,多学科融合不够,国外研究进展为国内研究提供了借鉴。未来应从我国具体国情出发,充分借鉴国外已有研究成果,逐步完善我国城市农业研究。第一,要丰富发展城市农业理论体系,尤其要充分理解新时代背景下城市化进程以及农业发展阶段对城市农业发展的需求与定位,明确未来发展方向;第二,融合RS、GIS等技术开展定量化研究,加强定量化技术方法的应用,弥补目前偏定性研究的缺陷;第三,加强多学科、多部门的协同,推进城市农业与制度、文化及城市规划融合方面的研究,摆脱目前研究“农业谈农业”的不足;第四,从社会经济发展的多维视角,揭示我国城市农业发展中存在的冲突和问题,加强对影响机理及动力机制的研究,为管理部门制定科学高效的政策措施提供支持。
