- 摘要:
- 以长武农业生态试验区为例，采用地块为计算单元，探讨黄土高原沟壑区小区域范围内土地生产力估算。通过对各地块光、热、水、肥等生态因子对小麦、玉米两个主要作物产量效应分析，计算了试验区耕地生产潜力。并且结合试验区人口及人口消费资料，估算出试验区人口容量。
- Abstract:
- Taking Changwu agro-ecology experimental station as an example,the yield effectiveness of ecological factors is analyzed. These factors include sunshine,temperature,water and soil fertility,etc.,which affect the yield of crops such as wheat and maize. and the potential productivity of cultivated land resources is calculated based on landpatch units within the small watershed of the loess plateau-gully region. Then population carrying capacity of land resources is estimated according to the consumption levels.
