岷江上游半干旱区耕地生产潜力分析——以茂县静州村为例

PRODUCTION POTENTIAL OF FARMLAND IN SEMI ARID AREA OF THE UPPER BASIN OF MINJIANG RIVER

以茂县静州村为例，从几个主要影响因素出发分析了岷江上游半干旱区耕地的生产潜力。并对生产潜力的估算及其订正系数的依据方法有所改进，运用于分析之中，结果可行。计算结果表明，静州村耕地生产潜力平均可达１２４１３．４ｋｇ／ｈｍ２，目前产量仅有９０００ｋｇ／ｈｍ２。

Based on the result of studies on Jingzhou village in Maoxian county, Sichuan province, the authors analyze production potential of farmland in semi-arid area of the upper basin of Minjiang River by several chief interaction factors. Estimation of potential production and calculation methods of emendation factors were improved in the analysis. The calculated result shows that average potential production of Jingzhou village is 12 413.4 kg/hm 2. However, the yield of the area is only 9 000 kg/hm 2 at present, so it can be increased to a higher level.
