Mode and practice of land consolidation based on human-earth harmonization

Abstract: Based on the perspective of human-earth harmonization, we used the method of literature summary and case analysis method to analyze the idea, mode, and technological approaches of land consolidation, and tried to enrich the theory and practice of Chinese rural land consolidation in the transitional period. The results indicated that as land-use regulation pathway of positive feedback, land consolidation should be on the basis of structure optimization and functional integration of the 3 large spaces (production space, living space and ecological space). So, as the active response of social and economic development stage requirements, land consolidation of the transitional period should be necessary to persist in the goal orientations like these-to ensure grain and food safety, and promote agricultural modernization; to support new village construction and optimize urban-rural land use space; to establish ecological security pattern and promote ecology landscape service function. The achievement of these targets needs the support of land consolidation based on the perspective of human-earth harmonization, but not traditional land consolidation mode. There are 4 elements in this kind of new mode. Three elements like goals of land consolidation, key points of land consolidation, and operation pattern have to match with the structure and function of rural territorial space; behavior rationality, another element, has to reach an organic unification between the value rationality and the instrumental rationality. In the technical form, this mode follows intelligent fusion of 3 kinds of technical ways-the farmland integrated technologies of production space, the rural construction land reused technologies of living space, and the ecology landscape improving technologies of eco-space. When this mode was applied, the results on the study area indicated that the practice of land consolidation was more standard and orderly than the traditional, and the whole structure and function of rural territorial space was improved. In the 3 large spaces, the agriculture production conditions of production space was improved much, the proportion of moderate scale management area increased from 18.00% to 30.53% after consolidation, the number of cultivated land plots averagely reduced by 1.6 for every peasant household, the guarantee rate of irrigation increased from 29.68% to 51.22%, the comprehensive mechanization ratio increased from 42.50% to 61.80%, and the local characteristic advantaged industries developed at the same time; the rural settlement landscape of living space was optimized much, and a total area of 1.74 hm2 referring to 24 blocks of abandoned rural residential lands was reclaimed and reused to cultivated land and other agricultural land, as a result the rural landscape harmony, the farmland concentration, and the style and feature of settlement got further improvement; the eco-network structure of eco-space was restored and intensified, the eco-nodes and eco-galleries linking with the farmland, settlement, forest and grassland in the study area were perfected through maintaining the original rivulets, ponds, irrigation canals and drainage channels, field roads and production roads, and building new storage paddy fields, new impounding reservoirs, new desilting pits and new production roads, and finally one ecology landscape pattern characterized by the integration of 'dot-line-field' was weaved. In this pattern, the basic space pattern was composed of production core space, living core space and ecology core space, and the key links were constituted by ecological corridors, ecological jump islands, stepping stones, and ecological buffer areas. According to the above study, the mode of land consolidation based on a perspective of human-earth harmonization will be a really rational choice under the background of high pressure of man-earth relationship in China.
