摘要
[目的]根据贵阳市不同区域(乡镇)不同季节的气候规律,研究贵阳发展反季节(错季节)蔬菜种植的可行性和分区布局。[方法]以贵阳各气象站1971～2010年的气候资料和贵阳市1∶250 000地理信息数据为材料,运用GIS技术,根据蔬菜种类生产与气象条件的关系确定蔬菜农业气候区划指标。[结果]结合当地土壤类型、灌溉条件以及专家意见,通过建立各气候要素与地理地形因子(经度、纬度、海拔高度)的关系模型,将各气候因子推算订正到乡镇点上,从贵阳市乡镇气候条件的时空分布规律分析出发,再根据贵阳市蔬菜种植的实际情况,提出了贵阳市蔬菜种植在发展正季的同时可以大力发展反季节(错季节)蔬菜,以解决贵阳市蔬菜淡季的问题;并对不同季节蔬菜种植的合理布局以乡镇为单元进行了气候适应性分区。[结论]该研究为贵阳市可大力发展反季节(错季节)蔬菜生产和充分合理利用蔬菜气候资源、因地制宜调整蔬菜产业布局提供了理论依据。
[Objective]To study the feasibility and partition layout of planting anti-season vegetables according to the climate laws of different seasons in disparate regions of Guiyang,[Method]Based on the data from each meteorology station in the 40 years（1971-2010） and 1∶250 000 geographic information data,using GIS technology,the climate districts index was determined according to the relationship between vegetable production and weather conditions.[Result]Considering the local soil types,irrigation conditions and the experts’ advices,via establishing a model of the relationship between the climate factors and geographic terrain factors（latitude,longitude and altitude）,various climatic factors were projected to the township point,embarking from the analysis of temporal and spatial distribution of climatic conditions of Guiyang,and according to the actual situation of vegetables planting in Guiyang City,it was proposed to actively develop seasonal as well as anti-season vegetables in order to solve the problems of vegetables off-season in Guiyang.And the rational distribution of different seasonal vegetables planting has been partitioned according to their climatic adaptation at the unit of township.[Conclusion]The study provides the theory basis for developing anti-season vegetables and taking full advantage of the vegetable climatic resources to adjust the layout of the vegetable industry of Guiyang according to local conditions.
