  • 摘要: 科学地划分农业生态类型区对于分类指导农业生产、合理利用农业资源具有重大的现实意义。本文通过相关分析,选择了包括自然本底、经济条件、生态环境和生态经济效益在内的26个指标,采用聚类分析的方法,把全省划分为四个生态类型区,即山区林地生态区(Ⅰ)、盆地丘陵生态区(Ⅱ)、水网平原生态区(Ⅲ)和沿海岛屿生态区(Ⅳ)。在分区的基础上,分别对各生态类型区进行了综合评述。

     

    Abstract: The topography of Zhejiang Province is distributed from southern Zhejiang to Northern Zhejiang Province in mountainous, hill, basin and plain areas respectively. There are great differences among these areas in agro-ecological environment, industrial structure, and e-conomic development. Rigorous classification of agro-ecological regions is critical for sustainable agricultural production and rational use of agricultural resources. With the method of cluster analysis, this province is divided into four ecological regions on the basis of 26 indexes representing natural resources, economic, ecological environments and economic efficiency. These ecological regions are: mountain forestry ecological regioni basin hill ecological region; plains river network ecological region and coastal island ecological region. A comprehensive evaluation of these ecological regions is made based on the regionization.
