Based on the aspects of ecology, social resources and economic technology, this paper aims at constructing the evaluation index system of land comprehensive carrying capacity of the Pearl River—Xijiang River economic zone by using entropy weighting method, pursuing the coupling coordination degree through calculating the land comprehensive carrying capacity, exploring the orderly equilibrium system and its differences. The results show that: (1) the overall carrying capacity of the urban agglomeration of the Pearl River—Xijiang River economic zone maintains good level in spite of several shortcomings and improvement space for the economic and technical carrying capacities; (2) the overall level of coupling degree of land comprehensive carrying capacity in Pearl River-Xijiang River economic zone remains the low level with feature of unbalance between the western area and eastern area; (3) the main problem lies in the gap between the city’s eco-environmental carrying capacity sub-system and the economic & technological sub-systems; (4) the internal operation of the system cannot effectively constitute the conducive force for the orderly operation and sustainable development; (5) by adjusting the intensity of land development and utilization, speeding up industrial transfer as well as implementing of ‘farmland off-site insurance’ etc., the land comprehensive carrying capacity of Pearl River—Xijiang River economic zone and the orderly development of its system can be promoted.
