南阳地处南北气候过渡地带,气候复杂多变。加之过去对自然资源不合理的开发利用,森林资源惨遭破坏,造成严重的水土流失,大多山丘区土层变薄,地力衰退,库河淤积,耕地被毁。建国40多年来,全市主要粗泥沙河道,普遍淤积抬高1—2米,水冲沙压,毁掉耕地数十万亩,每年因水土流失而造成的经济损失达5亿元。南阳的水土资源又相对匮乏,1985年,全市人均耕地1.1亩,山区人均耕地仅0.7亩。南阳市委、市政府的决策者充分认识到,发展南
Nanyang is located in the north-south climate transition zone, the climate is complex and changeable. Coupled with the irrational exploitation and utilization of natural resources in the past, forest resources were trashed and caused serious soil erosion. Most of the hillsides became thinner, the land was in recession, siltation of the Kuhe River and farmland were destroyed.
