Abstract:The research on constraint-region types of national resources and environment carrying is one of the essential works for industrialization and urbanization development in China. Based on the key indexes, such as per-capital potential of available land resources, per-capital potential of available water resources, degree of environmental stress, and degree of ecological restriction, this article builds up step-by-step or integrated measuring method, to measure the constrained carrying elements of water, land resources, environment, and ecology, to analyze spatial differences, and to classify areal types, which according to the unit at the county level. The results show the followings. (1) Almost 90% of territory has been in strongly constrained status in terms of resources and environment, and nearly half of them are strongly constrained by double elements, mainly distributed in intensive populated and industrial areas of the east of the Helan Mountain-Longmen Mountain line. (2) Eastern and central China's densely populated areas and Tibet Plateau has been in strong constraint of land resources shortage; North China, Northwest, Northeast, Sichuan Basin, and some southern cities are facing strong water shortage constraint. North China Plain, Yangtze River Delta, Northern Jiangsu, Sichuan Province, Chongqing Municipality, Guizhou Province, Guangxi Province, Northeast Plain, and Northern Loess Plateau have reached high constrained degree of environmental stress. Strongly ecological constraint area is mainly concentrated in the southwest of Tian Mountain-Dabie Mountain line. Besides, on the northeast of the line, the Loess Plateau, Alashan of Inner Mongolia, Northeast China, and coastal area of northern Jiangsu are also shared by the same constraint. (3) The elements of constraints of national resources and environment carrying are diversed crisscross. The multi-elements spatial distribution is relative centralized. Except Tibet Plateau, which is the land resources-ecological constraint, other cross constraint areas are mainly distributed in the east of Helan Mountain-Longmen Mountain line. (4) Aiming at the feature of constraints, such as broad coverage, complicated and Industrial concentrated areas overlapping with heavily populated areas, during the 13th Five-Years Plan, our nation is appropriate to intensify efforts on mining national conditions database, on monitoring and early-warning of the national resources and environment carrying capacity, on researching basic evaluation theory method of capacity, and on perfecting the system of national spatial regulation.
