针对鄱阳湖地区油菜生产的特点,对影响油菜生长和产量形成的气象条件进行分析,并建立油菜气候区划指标.根据鄱阳湖地区1961～2005年油菜生长季气候要素分析显示,影响该区油菜生长发育的主要气候要素为降水和日照条件,关键生长发育期为播种出苗期和开花结荚期.采用1: 5万数字高程模型(DEM)和GIS空间分析,将影响油菜生长的关键气候要素插值生成分布式数据,并根据建立的油菜气候区划指标对鄱阳湖地区油菜种植进行区划.结果表明,除鄱阳湖滨湖区及湖区的南部为油菜种植一般区外,其余地区均为油菜种植的最适区和较适区,尤其鄱阳湖地区北部,为油菜种植的最佳区.

In view of the rape planting characteristics in Poyang Lake area,this paper analyses the effect of meteorological conditions on rape growing and yield formation, and builds the climate division index of rape planting. The meteorological data analysis of rape growing seasons during 1961 ~2005 year in Poyang Lake area , indicates the climate factors affecting rape growing are mainly precipitation and light. The key growing periods of rape are the sowing to seedling stage and the blossom to pod stage. Using digital elevation model ( scale 1:50 000) and GIS spatial analyses, the key factors of climate affecting rape growing are interposed and the distribution data of climate are produced. The paper divides rape planting in Poyang Lake area by climate division using the index of rape climate division and the result of division shows that Poyang Lake area is suitable for rape planting except for the shore and the southern of Poyang Lake area, the northern part is the most suitable for rape planting.
