Abstract: China's natural resources are quite rich. Yet, owing to a very hrge population, per capita share of different natural resources is rather low.Major factors governing the formation and distribution of different resources include: a vast territory, a mid-latitudinal and east-coastal location, the mountainous landform and the huge impact of human activities. These factors are closely interrelated and usually work together.Most renewable natural resources, including arable land resources, climatic resources, water resources and biological resources are mainly distributed according to the integration of horizontal zonation (mainly determined by temperature and moisture elements) and vertical zonation (mainly determined by topography and landform elements); azonal factors such as geological structure and human impacts are sometimes also significant. Mineral resources which are non-renewable are mainly determined by geological structure and thus distributed very unevenly.Different natural resources are thus characterized by their close interrelationship and conspicuous areal differentiation. Consequently, they should be developed comprehensively by an overall planning.
