黄淮海平原农区县域土地利用景观格局分析及可持续利用建议

研究目的:系统分析黄淮海平原农区土地利用景观格局特征存在问题、形成机制及其优化调整思路。研究方法:用地理信息系统支持下的景观生态学格局定量分析方法,以土地利用现状图为工作底图,系统研究了曲周县的土地利用景观的空间格局指标。研究结果:曲周县的土地利用景观格局在我国广大农区具有代表意义,是我国农村土地利用方式及高人口密度综合作用的结果;景观人文干扰强,耕地在整个景观中占首要位置,水浇地、旱地和居民点的优势度明显高于其他景观类型。研究结论:应用景观生态学方法可以为土地可持续利用管理评价提供新的方法和视角,最后提出了以加强沟渠、防护林等廊道建设和促进农村城市化的平原农区优化景观格局的建议。

Landscape Pattern Analysis at County Level in Huang-Huai-Hai Plain and Suggestions for Sustainable Land Management

The purpose of this paper is to analyze the landscape pattern characteristic and its evolvement mechanism, and the problems in land use of Quzhou county , which is located in agricultural zone of Huang-Huai-Hai Plain. GIS and landscape pattern quantitative analysis methods were employed. The results indicate that landscape pattern of Quzhou county is strongly shaped by human activities and cultivated land is dominate of whole landscape. Meanwhile, irrigation land, dry land and rural residents play preponderant roles in Quzhou county. This pattern is a typical model in Huang-Huai-Hai Plain, which has been resulted from land use type and higher population density. This method could offer new idea and method for assessment of sustainable land management. Finally, some suggestions are put forward to optimize landscape pattern and actualize sustainable land management, including strengthening landscape corridors construction and fulfill the target of sustainable land management, which include strengthening landscape corridors construction and promoting urbanization.
