河西冷凉灌区农牧结合户效益分析——以武威市新华乡头坝村和新华村为例

Benefit analysis for combination of farming with animal husbandry in cool irrigation area of Hexi--Case studies from Touba and Xinhua villages of Xinhua Township,Wuwei City

  • 摘要: 对河西冷凉灌区3O个农户生态系统进行了聚类分析,将农户分为养种、种养和种植型,并对其经济、社会、生态和综合效益进行分析。各效益指标均呈现养种型最优、种养型次之、种植型最低的规律。能量和物质转化率及土壤养分含量表明,增加畜牧业投入,可显著提高农业生态系统的产出和效益。

     

    Abstract: Thirty household ecosystems in cool irrigation area of Hexi were classified into uhree types by cluster analysis,that are livestock rising+planting type.planting+livestock rising type and sole panting type.The economic,social, ecological and comprehensive benefits of the 3 types were analysed.According to benefit index live stock rising+planting type had the highest benefits.planting+livestock rising followed as the next,sole planting type had the lowest benefits.The energy and material conversion rate as well as soil nutrient contents showed that increasing the input in animal husbandry can improve output and benefits of agroecosystem.
