前言新西兰位太平洋西南部,是一个多山的国家,由北岛、南岛及一些小岛组成。山脉纵贯全岛,有几座3000米以上的高峰。由于多山,河流短,故流速大,急滩多。北岛为暖温带气候,南岛为凉温带气候。除南岛南阿尔卑斯山脉小面积半干躁区域外,全境为海洋性气候。年雨量1000-2500毫米。雨量分布均匀,夏季有时有短期干旱。约150年前,欧洲移民来到时,新西兰大部分(66％)为茂密森林和矮灌木林。森林被迅速开发,烧后一律播种外来草籽,把森林变为农场,形成大面积草地730万公顷,草地灌丛和草
Introduction New Zealand is a mountainous country in the southwest Pacific Ocean. It consists of North Island, South Island and some small islands. Longitudinal across the island mountains, there are several 3,000 meters above the peak. Due to mountainous, short rivers, so the flow rate, acute and more beach. North Island is warm temperate climate, the South Island is cool temperate climate. In addition to the southern island of South Alps semi-dry area of small area, the whole territory of a maritime climate. Annual rainfall of 1000-2500 mm. Rainfall is evenly distributed, sometimes short-term drought in summer. About 150 years ago, when immigrants from Europe came, most of New Zealand (66%) were dense forests and dwarf shrubs. The forest was rapidly developed and all foreign seeds were planted after burning, turning the forest into a farm, forming a large area of 7.3 million hectares of grassland, grassland shrubs and grass
