半干旱区农业水资源平衡及生态农业规划初探—以吉林省西部为例

A preliminary study on the agricultural water resources balance and eco-agriculture program in a semiarid regi0n— A case study from the west area of Jilin Province

  • 摘要: 根据可利用水量及各农业要素需水量变化,以改善农业水资源平衡、提高系统生态效益为核心,用线性规划调整农业生态结构的研究结果表明,适当压缩耕地面积,扩大人工林、草地和水域面积,可稳定粮食产量和农业经济效益,明显缓解水供求矛盾,改善农业生态环境,提高系统生态效益。

     

    Abstract: According tO the balance condition between supply and demand of agricultural water resources ,in order tO improve the agricultural water resources balance and rise the ecological benefit of the agriculture ecological system ,the struc-tttre of the system WaS regulated by using linear programming.The results show that the shortage of the water resources and the agricultural coo-environment can be improved and the ecological benefit of the system can be risen obviously by cutting down the farmland area suitably and expanding the artificial grass,forest and waters area,and the stability of the grain output and agricultural economic benefit at present may be kept.
