松嫩平原西南部——半湿润地区/半干旱地区再议

RE-DISCUSS ON THE SOUTHWEST OF SONGNENPLAIN-----SEMI-HUMID AREA OR SEMIARID AREA

本文仅就松嫩平原西南部,对以往的区划方案中把其归为半湿润地区有不同认识,并分别从区划原则、区划方法、区划指标上论述其应归属于半干旱地区的合理性.进一步提出了该区的土地利用发展方向.

I have sonic different ideas from previous natural divisions on the southwest of Songnen plain. I think this area more like semi-arid area than semi-humid area. This paper discussed the reasonableness diagnose the southwest of Songnen plain as semi-arid area. Based on the natural division principles, the natural division means and the natural division norms. Accordingly, guide the agriculture development of this area.
