Research On Regionalization For Land Reclamation Based On Theories Of Landscape Ecology

China is now in a critical period of rapid economic development, and the dominant direction of social economy development in countryside is converting to rural urbanization, agricultural modernization and urban-rural integration. In this process, the lag of rural land planning and land reclamation make that rural land uses be in a structural unreasonable situation, and lead the ecological environment be out of line, which had cost the rural land use fragmentation, ecological function degradation, rural landscape damage occurred from time to time. All above had caused the wide attention of society. Land remediation plays a very important role in promoting rural social economic development, alleviating the contradiction between supply and demand of land resources, and strengthening the protection of arable land and the new rural construction. However, the rural land renovating in most areas is lack of landscape ecology theory, which results in the original village rural atmosphere’s disappearing, ecological landscape’s destruction, and biodiversity reduction, and brings serious effect to rural logical environment and sustainable development. These problems will bring a new challenge to the new round rural land reclamation. Therefore, it is of great significance to research in land reclamation based on ecological landscape theory.This paper is divided into six parts. The first part introduces the research background, the target significance, domestic and foreign research, research contents, research methods and research technique route; The second part discusses the related concepts and theories of landscape ecology; the third part is about the study of rural land punish landscape classification method; the fourth part analyses of landscape index selection, calculation and establishment of the index system; the fifth part takes Yunmeng County as an example, the research area of landscape classification, selection of landscape index and calculation, and then establishes a system of evaluation index, to Yunmeng County land reclamation suitability evaluation after grading, according to the suitability grades for the study of regional partition, and to put forward measures and suggestions for the related regulation; the sixth part is the conclusion and the deficiency in this paper and the research prospect.
