| 摘 要： | 在GIS的支持下,计算了松嫩平原各县市主要作物的农业气候生产潜力,并分析了各地农业自然资源利用率的空间差异。结果表明,松嫩平原各地光合潜力差异不大;由于南北跨度大,各地光温潜力差异较大,且从北到南呈带状增加趋势;由于各地作物生育期内降水呈地带性分布,使得各地气候生产潜力具有较大差异,并呈由西向东逐渐增加的趋势。各地主要作物农业自然资源利用率差别较大,西部地区资源利用率较低,增产潜力巨大。

| Abstract: | Supported by GIS,the agricultural climatic potential productivity of the main crops for all counties in the Songnen Plain was calculated.The spatial differences on agricultural and natural resources utilization ratios in the region were ana-lyzed.The results showed that there were no significant differences in photosynthesis potential productivities among different locations,whereas due to large latitude span the photosynthesis-temperature potential productivities increased from the north to the south significantly.As the rain belt distribution showed a significant difference in the different counties,this led to an increase of the climate potential productivity from the west to the east gradually.There were significant differences in agricul-tural and natural resources utilization ratios of main crops in the different counties of the plain.The resources utilization ra-tios in the western parts of Songnen Plain were lower than that in the eastern parts,where showed in turn a large potential to increase the yields. |
