摘要
中国农业资源环境问题日益突出,地域分异明显。中国农业资源环境分区数据按区域农业生产特点、适宜性及环境问题,将中国陆地特定的地域空间单元划分为不同的农业资源环境分区。本分区以县域为制图单元,采取二级分区方法,其中一级区依据气候条件和大地构造的地域分异划分为10个区,二级区根据水资源、土地资源和环境条件问题差异,划分出57个二级区。分区方法是在农业资源环境要素综合分析基础上的主导因素法。分区的命名以简单明了通俗为原则,一级区主要依自然地理区位命名;二级区的命名结合地理区位和地貌类型命名。
The challenges from agricultural resources and environment have become increasingly prominent in China,but vary considerably by region.The dataset of agricultural resource and environment zoning of China was produced according to the agricultural production characteristics,suitability and environmental challenges.It is divided the specific regional spatial units of territories into different agricultural resource and environmental zones of China.Using the county as the basic mapping unit,the zoning is consisted of two levels.The ten first-level zones were identified according to regional differences in climate and geotectonic characteristics at the macro scale.Next,fifty-seven second-level zones were differentiated according to water resources,land resources,and environmental conditions.The zoning method is a dominant factor method based on comprehensive analysis of agricultural resources and environmental factors.The naming of the zones is based on the principles of simplicity,clarity and popularity.The first-level zones are mainly named according to the physical geographical location,and the naming of the second-level districts is in conjunction with geographic location and landform types.
