山西沙棘经济林生态区的初步划分

Preliminary Division of Ecological Region of Seabuckthorn Forest in Shanxi Province

根据沙棘的生态生物学特性，以降水量、温度和光照等条件为主导因素，遵循地域分异规律，以不同山系为中心，沙棘果实丰产为前提，将山西划分为六大沙棘经济林生态区，即晋北苍头河流域沙棘经济林生态区，晋西北芦芽山──云中山沙棘经济林生态区，晋西关帝山沙棘经济林生态区，晋东北五台山沙棘经济林生态区，晋东太行山沙棘经济林生态区，晋东南太岳山沙棘经济林生态区。当前的主要任务是：把沙棘经济林生态区建成沙棘果实商品生产基地，开展沙棘丰产栽培技术研究，提出完善的栽培技术体系；分区建设良种选育繁殖基地，提供专业化良种；根据沙棘资源蕴藏量和生产潜力合理布局加工业，开展沙棘遗传资源的收集和研究，为沙棘选种提供物质基础。

On the basis of eco-biological property of Seabuckthorn plant, combining the rainfall,temperature and illumination of different mountain systems, the seabuckthorn forest in Shanxi province was divivded into 6 ecological region:①Cangtou River valley ecological region;②Luya Mountain and Yunzhong Mountain ecological region;③Guandi Mountain ecological region;④Wutai Mountain ecoological region;⑤Taihang Mountain ecological region;⑥Taiyue Mountain ecological region. This work provided the foundation for exploitation and utilization of seabuckthorn resource in future.
