浙江省草山草坡的特点及其开发利用战略——以常山县为例

THE CHARACTERISTICS OF GRASS MOUNTAINS AND GRASS SLOPES AND THEIR EXPLOITATION AND UTILIZATION STRATEGY IN ZHEJIANG PROVINCE——A CASE STUDY IN CHANGSHAN COUNTY

浙江省草山草坡分布广泛,是一项重要的农业自然资源。通过对常山县草山草坡的调查研究。本文认为草山草坡不仅面积大,而且类型多样;宜牧饲草种类虽多,但营养含量较低;产草量虽高,但适口性较差,利用期很短;分布地坡度陡,水土流失严重。所以,在开发利用时,应贯彻开发与整治、利用与保护相结合的原则,促进生态—经济系统的良性循环,实现生态、经济、社会三效益的同步增长。为此,提出了3点建议。

The grass mountains and grass slopes widely distribute in Zhejiag Provnce are an important natural resource of agriculture. On the basis of the investigation and study of the grass mountains and grass slopes in Changshan County, this paper considers that not only their distributive area is extensive but also their types are various. The kinds of fodder grass suitable for pasture are abundant, but their nutrition content is rather low; the grass yield is great, but the palatable property is not so good; and the utilization period is very short. Besides, the gradient of the distributive area is steep and the soil erosion very serious. So, at the time when we exploit and use the grass mountains and grass slopes, we should carry out the principle of integrating exploitation with renovation and integrating utilization with protection and promore the good circulation of ecological-economic system. Then, it is possible to realize the simultaneous increase in ecological benifit, economic benifit and social benifit. For this purpose, three proposals are put forward in this paper.
