| 摘 要： | 借助地理信息系统和数学模型集成技术,利用福建省气象观测资料推算出全省年均温度、降水量和实际蒸散量 125m×125m空间栅格数据,进而探讨全省林地气候潜在生产力空间分异及其分区.结果表明,福建省林地气候潜在生产力为1163. 8-2455. 4g·m-2·a-1,其空间分异呈现由低海拔向高海拔以及由闽南向闽西、闽中、闽北和闽东递减的趋势.全省林地以高、中气候潜在生产力区占优势,分别占全省林地总面积的 68. 32%和 30. 46%.

| Abstract: | Based on geographic imformation system (GIS) technology integrated with mathematic models, 125 m×125 m grid data of annual mean values of temperature, rainfall and actual evaporation capacity in Fujian were calculated by weather observing materials, the grid data of climate potential productivity (CPP) of forestry land in Fujian were calculated and the CPP variance and division were then discussed. The results showed that the CPP of forestry land in Fujian ranged from 1163.8 g·m~(-2)·a~(-1) to 2455.4 g·m~(-2)·a~(-1), which decreased from low to high altitute areas and from South Fujian to West, Middle, North and East Fujian. The areas of high and medium CPP of forestry land in Fujian were superior, which were 68.32% and 30.46% of the total, respectively. |
