| 摘 要： | 以陕南商洛地区为例, 选取适当的农业气候区划及垂直分层指标, 利用GIS空间分析及制图功能, 在实现指标空间化基础上, 采用模糊综合评判方法, 实现山区农业气候垂直分层。结果表明:商洛地区在不同气候带内可分别划分3个垂直气候层:北亚热带山区有温热易旱层 (低于700 m)、温暖半湿润层 (750~1250 m) 和温凉冷凉湿润层 (1250~1800 m); 暖温带山区包括温暖易旱层 (800~1100 m)、温凉半湿润层 (1100~1500 m) 和冷凉湿润层 (1500~2500 m)。并对各层适宜发展农业生态类型进行了评述。

| Abstract: | The agrotopoclimatic vertical zoning based on GIS is carried out by fuzzy comprehensive assessment. Shang-luo mountainous area is taken as an example, which is in the east of the south slope of Qinling Mountains in Shaanxi Province, and which belongs to the semi-humid mountainous climate transition from warm extratropical to subtropical zone.The heat index for vertical zoning is used to resemble the general characteristics and the regional differences by four kinds of spatial grids database. Cumulative temperature greater than 10 ℃, average extreme lowest temperatures, mean temperatures of the coldest mouth and mean temperatures of the warmest mouth are included. Before the indexes are spatially interpolated by inverse distance weight (IDW), they are emended to the same height above sea level via the lapse rates with the help of digital elevation model (DEM), which are based on sectional observation data in subtropical west mountainous regions in Qinling and Bashan.With the overlapping function of GIS, the graph of comprehensive zone of agro-climatic resources in Shangluo mountainous region based on GIS is made by superposing vertical zone grids with aridity grids in growth season and north subtropical boundary vector, using the combined function of the GIS.According to the comprehensive division graph made by GIS, three layers are divided into two climatic zones in Shangluo area:hot layer with easily drought tendency ( < 700 m), warm and semi-humid layer (750—1250 m), mild-cold and cool-cold humid layer (1250—1800 m) in subtropical zone. Warm drought layer with easily drought (800—1000 m), mild-cold and semi-humid layer (1100—1500 m), cool-cold and humid layer (1500—2500m) in warm extratropical zone. The naming for the vertical zoning reflects the horizontal and vertical climate characteristics of the Shangluo region, and the economic development direction in each layer. |
