西南丘陵区标准化蔬菜基地规划与工程设计研究

Planning of Standardized Vegetable Base and Engineering Design in Hilly Region in South-west China

"菜篮子"工程是事关民生的基础工程,各级政府高度重视,蔬菜基地标准化建设对于蔬菜产业可持续发展尤为重要。本文结合重庆市璧山县璧北蔬菜基地核心示范区建设实例,宏观阐述标准化蔬菜基地建设必须遵循可持续农业方向,符合生态化,设施化,观光休闲化,生加销一体化的发展趋势,。微观探讨工程设计要点,确定条田设计方法和主要灌排形式,即地形起伏较大时,条田田块适宜局部平整,条田规划首先满足灌溉和机耕要求,田间灌渠采用横向布置形式;而地形相对平坦时,则适合大规模的耕作区划分,应更多考虑排水问题,田间灌渠采用灌排结合纵向布置形式。因此,以标准化蔬菜基地产业建设为目标的规划设计必须立足其复杂多样的立地条件和功能分区差异,配套不同的土地平整和灌排体系工程,实现土地资源的高效利用。

＇Vegetable Basket Project＇ was a foundation of citizens＇ daily life,and attracts more attention from the government in different region.With the development of economy and the progress of science and technology, constructing standardized vegetable base was becoming more and more important.Based on the construction of standardized vegetable base in Bishan,Chongqing as the study case,this paper expatiated that standardized vegetable base planning must follow the direction of the sustainable agriculture development to accord with the four developing trends of the continuous agriculture i.e ecologization,hi-tech,factory production,sight seeing, integration of sale and production from macrostructure.Addition to that,it also discussed the main principle of engineering design at macroscopic level,and confirmed the design method of strip field and the main form of irrigation and drainage.The results showed that： first,in areas of steep terrain it was more suitable to level locally,while in relatively flat areas it was preferable for large-scale farming area division;secondly,in undulant area the design of terrace should first meet the demands of irrigation and mechanized farming, furthermore,the horizontal layout should be adopted in the disposition of irrigation channels,while in flat area the disposition of irrigation channels should adopt vertical layout with more consideration of drainage problems. Therefore,with the purpose of constructing standardized vegetable base,the design was proposed according to the complex and diverse geographical conditions and different functional areas,moreover,it should introduce various land leveling project and different irrigation and drainage system to realize the efficient use of land resources.
