地理信息系统在浮梁县甘薯生产的气候条件分析及区划中的应用

Analysis and Regional Application of GIS on Climatic Conditions of Sweet Potato Production in Fuliang County

介绍了甘薯生长对气象条件的要求，运用统计方法分析了影响甘薯产量的气象条件。根据甘薯种植对气象条件的要求，确定将15℃初日～10℃终日之间的间隔日数作为浮梁县甘薯种植的区划指标，运用统计分析方法计算浮梁县15℃初日～10℃终日之间的间隔日数随经度、纬度和海拔高度的变化情况，利用地理信息系统将浮梁县甘薯分为最优区和适宜区，其中浮梁县南部条件较好，可发展双季种植。

The request of sweet potato growth to the meteorological condition was introduced. The meteorological condition influenced sweet potato yield was analyzed by the statistical method. According to the sweet potato planter to the meteorological condition request, the interval date number between 15 ℃ the first day and 10 ℃ the last day was determined as the planter regionalization index of sweet potato in Fuliang County. The change of the interval date number along with the longitude, the latitude and the altitude above sea level was calculated. Fuliiang County sweet potato planting region was divided into the superior area and the suitable area by using the geographic information system. The climatic condition was good in the south of Fuliiang County, it could develop the double season planting.
