- 摘要:
- 用偏离—份额分析法对蒙普河小流域治理后农业经济结构的合理性进行了定量分析评价；用粮食与经济人口承载量的几何平均数分析了土地人口承载能力的变化情况。结果表明：通过综合治理，小流域的农业经济结构得到了较为合理调整，各产业部门的竞争能力明显提高，经济增长速度高于全省平均水平；人口承载量从治理前的108人/km2提高到228人/km2，提高了111.4%。
- Abstract:
- The rationality of agricultural economic structure about comprehensive management of small watershed at the Mengpu River was assessed quantitatively based on Shift-share method;the change of population-carrying capability was analysed by the method of geometry average about grain and economy.The results showed that the agricultural economic structure has made rational adjustments,the capacity of competition of production departments were raised obviously,the growth speed of economy is higher than the average of Guizhou Province;the population-carrying capability raised to 228 man/km2 from 108 man/km2.
