Study On The Differences And The Comprehensive Coordination Of Land Consolidation And Rehabilitation On Different Spatial Scales

Making and coordinating the formulation and implementation management of landconsolidation and rehabilitation planning of different levels are of important theoretical andpractical significance. From the functions of land consolidation and rehabilitation, the essayanalyzes the scale difference between land consolidation and rehabilitation planning ofdifferent levels, makes explicit the functional orientations and work division of landconsolidation and rehabilitation planning of provincial, city and county levels, and takingthe whole situation into consideration, coordinates land consolidation and rehabilitationplanning with different scales from the aspect of planning indicators and space. The essaycomes to the following conclusions:（1）Analyze planning scale difference on the basis of land consolidation andrehabilitation planning functions and hierarchy. The provincial planning guides the policyorientation. The city level planning is mainly about layout and overall arrangement. Andthe county level planning is more like an implementation document that guides landconsolidation and rehabilitation activities in the county. Due to the difference in functions,interest of stakeholders, basis data of plans with various scale, the aims and targets as wellas content of different plans are not the same. The larger scale of plan is, the more itemphasizes on policy making and macro-control. The smaller the scale of plan is, the moreit emphasizes on operability and micro-implementation.(2) Establish the configuration of land consolidation and rehabilitation plans ofdifferent scale as a whole from the aspects of aims and targets, space and projects.The land consolidation and rehabilitation indicator system should have clear gradationand good space-time arrangement. The aims and targets set in the plans of higher level shallcontrol relevant indicators in the plans of lower levels. Large scale land consolidation andrehabilitation plan shall put forward relevant restraining indicators, reflecting landconsolidation and rehabilitation strategic arrangement and policy guiding. Medium scaleplan indicators shall reflect land consolidation and rehabilitation zone functions and variousorientations. Small scale plan shall emphasize space implementation, reflecting impacts ofeach indicator on land utilization space rearrangement.Overall space connection should be accomplished through the connection of differentscale’s land consolidation and rehabilitation zones. Plans at province level shall dividezones comprehensively, arranging important projects, embodying guidance on functionzone partition of cities; city plans shall make functions zone partition of land consolidationand rehabilitation, arranging important projects, laying stress on the overall coordinationand arrangement of all partition zones, embodying the nature of policy guiding; under thecontrol of functional partition of zones, evaluating land use pattern，quality and ecologicalsuitability, analyzing the relationship between different type’s land consolidation andrehabilitation potential and zone functions, delimiting land consolidation and rehabilitation project zones.（3）Taking Zhejiang province as example, carry out land consolidation andrehabilitation planning overall coordination empirical study from the aspects of indexdecomposition and space.Taking capital farmland decomposition as example, carry out decomposition ofplanning indexes, realizing gradual scale control and connection of planning indexes.Results prove that main influence factors of provincial indicators are grain productioncapacity based on capital farmland areas and cultivated land quality; apart from affected bycapital farmland area, city index decomposition, affected also by consolidation potential;county indexes decomposition affected mainly by landscape scale cultivated land and ruralconstruction land. The affecting index not only embody continue of higher level planningindexes, but also internal difference of its own level.Taking method of from top to bottom, layer by layer control, delimiting differentlevels’ land consolidation and rehabilitation zone partition, carry out overall coordination ofspace. According to zone macro difference, dividing Zhejiang province into ZheBeiShuiWang plain zone, ZheXi mountainous and hills zone and so on. Make sure policy andspace orientation of different fictional zone partition. And then according to landconsolidation and rehabilitation position disparity in Jiaxing, dividing Jiaxing city intofeatured agriculture development zone, cities and towns optimizing consolidation zone, andwet land and waters ecological function zone. Finally combining different kind’s landconsolidation and rehabilitation potential of Nanhu district, delimit capital farmlandconstruction project zone, rural construction land consolidation project zone, and rural landcomprehensive consolidation project zone, directing reasonable arrangement of landconsolidation and rehabilitation projects.
