四川省西部山区农作物生产潜力研究——以石棉县为例

Study of productive potential of crops in western mountainous regions of Sichuan——A case study of Shimian

在分析石棉县自然条件的基础上,对该县农作物的光合、光温、光温水及光温水土生产潜力进行了估算,并在计算农作物的土地自然生产潜力和实际生产力的基础上,结合石棉县农业生产存在问题,提出了石棉县农业可持续发展的对策.

Based on the analysis of its natural conditions, Shimian county＇ s productive potential of crop photosynthesis, and photosynthesis-temperature, photosynthesis-temperature-water and photosynthesis-temperature-water-land were estimated by comparing the standard of present productive force with theoretical productivities, Besides, in line with productive potentials and existing problems, countermeasures had been advanced for the agricultural sustainable development in Shimian.
