基于GIS的重庆市万盛区猕猴桃气候区划分析

The Kiwifruit Climate Division Analysis of Chongqing Wansheng District That Based On Geographic Information System

考察猕猴桃生长需要的生态条件,确定重庆市万盛区猕猴桃适宜种植区并对猕猴桃栽培提出建议。借助GIS平台,对重庆市34台站气温、降水、日照等数据采用克里金插值、反向运算等方法进行空间分析。研究发现万盛区光照和水分条件较充分;确定以年平均气温为区划指标,根据指标利用地理信息系统技术在1∶50 000地形上制作万盛区猕猴桃气候生态区划图。研究还显示万盛区大部分地区适宜栽培猕猴桃,其中海拔900～1 500 m的中海拔山区是热量适中的最适宜种植区;青年镇、关坝镇、金桥镇、丛林镇等地区为气候温暖适宜区;东部海拔1 500 m以上的望香台、寨子岩等高山地区为气候温凉适宜区。研究认为,在万盛区发展猕猴桃生产,可以采取以下措施:结合有利地势建立试验基地、采取适宜的栽培方式、利用"套袋"技术保护丰产丰收。

This paper investigates the meteorological condition of kiwifruit growth, ensures the appropriate planting areas of kiwifruit in Wansheng district and gives some cultivation suggestion of it. Based on the geographic information system platform, we used some methods of spatial analysis like kriging, inverse distance weighted to the temperature, rainfall and sunshine of Chongqing thirty-four stations. It has been discovered there are enough sunshine and moisture in Wansheng distract and we determined the mean of annual temperature was regionalization index. According to the regionalization index, the article works out the map with 1 ： 50 000 topographic data by the technology of geographic information system and names it Wansheng district climate ecological zonation of kiwifruit. The re- sults of the study show that most of the regions in Wansheng district are appropriate for planting kiwifruit. Among them the medium ele- vations of mountains that nine hundred meters to one thousand five hundred meters was named the most suitable areas because of it heat appropriate, the town of Qingnian, Guanba and Conglin were named A warm climate region, the eastern that altitude beyond one point five kilometers like Wangxiangtai, Zhaiziyan and other Alpine areas were called cool weather appropriate region. The research agree- ment that we should take the following measures to increase the production, combined with favorable terrain to establish test base, suit- able cultivation method and using the ＂bag＂ protection of high yield bumper harvest.
