摘要
本研究报告共划分9个气候带和1个高寒区域:在中暖温带中划分出7个湿润和干旱区(在个别省中也区分出旱、湿区未列入)。亚热带普遍湿润,因而未划分,旱湿区直接划亚区。共划分出52个亚区,其中有经济林生产的50个亚区。39个小区(有的亚区未分小区)。在原研究报告第三章,各带区特征作了综述。亚区是经济林生产单位,不仅有自然特征综述,并明确提出经济林生产项目的发展方向。
A cultural division with four categories, namely, climatic zone, dry/moist climatic region, dry/moist climatic subregion, and crop growing area was derived from various data including climate, geography, topography, vegetation, and nontimber forest crop production. Nine climatic zones plus one alpine cold region were assigned for the whole country. For the central warm temperate zone where precipitation and humidity vary remarkably from one geographic location to another, 7 dry and moist regions were divided. Altogether, 52 climatic subregions were divided, of which 50 are of an economic significance. Under these subregions 39 growing areas for nontimber forest crops were delineated.
