摘要
在计算光合生产潜力的基础上,采用逐级订正法,分别对西乡县平坝、丘陵、山区及全县平均状况的土地生产潜力进行了计算;并依据历史产量资料,按照潜力利用率的增长趋势,对未来粮食产量作了长期预测,按照切合实际的消费水平,计算出未来各年的人口承载量,并提出相应的措施。
This paper is based on the Calculation of the potentiality of the photosynthesis production. Level corrections is adopted earth clams, hills, mountain areas and the potential of the average production of the land in Xixiang County is calculated. Based on the records of the output and the growing tendancy of the utilization ratio of the potentiality, a long-term prodiction to the future output of grain is made. In accordance with the real standard of consumption, the anuual bearing capacity of the population is counted. Furthermore, appropriate measures are proprosed.
