Land consolidation spatial management (LCSM) has a significant influence on optimizing national territory arrangement in China. Constrained by the absence of proper administration and evaluation mechanisms, the current LCSM system is entirely based on the principle of "Spatial Recognition of Reserved Arable Land Resources", which eventually causes the loss of distinct management hierarchy and coordination between land consolidation functions and territorial functions. Aiming at providing an optimal path for LCSM in China, this paper proposes a new principle of "Spatial Coordination Guided by Land Consolidation Function" and establishes a new system consisting of national, provincial, municipal and county-level land consolidation zonings, which comprehensively cover the four key spatial elements of land consolidation (territorial function, land consolidation function, land consolidation potential and land consolidation engineering) by using a factor-combination method. Advantages of this new system are described as follows: (1) it recognizes a top-bottom dependent relationship and control mechanism inside LCSM; (2) it coordinates land consolidation functions with territorial functions to effectively promote regional development; (3) it actualizes multiple land consolidation functions with the support of various land consolidation potentials and engineering means; and (4) it provides specific and explicit guidance on single land consolidation project arrangement and coordinates the spatial arrangements of different regional land consolidation activities. To promote the realization of this new system, some important suggestions are also provided, such as establishing diversified and differentiated land consolidation evaluation systems; granting regions autonomy and flexibility over land consolidation project approval, investment and implement standards; and performing land consolidation with the entire region as a complete consolidation object. © 2014 Elsevier Ltd.

In order to profoundly understand the cultivated land quality, efficiently protect and improve cultivated land quality, the differential characteristic of cultivated land grade between provincial regions were found out by contrast analysis method based on the results of cultivated land gradation in China and the 1:50000 national agricultural land gradation database. The results showed that the basic differential characteristic of cultivated land in China was summed up as "less area of excellent grade, more area of low grade, and complex differential characteristics between and in provincial regions". The total cultivated land of 31provinces in China was calculated as 68390.2 khm2 by using the Standard Area defined as Guangdong Province's average grade(5.4 grade), or 45750.7 khm2 by using the Standard Area defined as 1 grade. According to the primary farmland protection area of 31 provinces in 2020 in national land use planning, primary farmland protection ratio by law and cultivated land grade in provinces must be plan as a whole. Based on the results, it is suggested that both quality and quantity should be paid attention, and taking grade advance and land capability construction as core role, constituting cultivated land grade and land capability dynamic inspection and report system are all necessary in land rehabilitation programming system, primary farmland regulating, high criterion primary farmland construction and permanence primary farmland protection.
