【摘要】 人类进入21世纪,土地利用与生态环境的关系日益受到重视。随着经济发展突飞猛进,城市建设日新月异。强烈的土地需求对土地利用的强度、方式、规模、布局等造成了深远的影响,同时也对生态环境造成强烈的冲击,生态安全受到严重威胁。为了确保生态安全,实现经济与社会的可持续发展,必须把协调土地利用与生态环境的关系放到十分突出的地位。如何既保障经济社会发展的土地需求,促进经济社会的全面发展,又兼顾环境保护和生态建设,促进社会的和谐和可持续发展,给土地利用提出了新要求。本文通过对河南省周口市土地利用与生态环境的协调发展状况进行研究,提出了一系列协调土地利用与生态环境的对策,以期为周口市土地生态安全建设提供科学依据,进而促进土地利用与生态环境的可持续发展。论文主要包括六章内容,其中:第一章首先论述了本文的研究背景和立题意义,概述了国内外协调土地利用与生态环境关系的研究进展,进而提出本文的研究内容、研究方法和技术路线。第二章对周口市区域情况进行概述,主要是自然地理、自然资源和社会经济发展三个方面进行分析。第三章分析了周口市生态环境现状,识别与土地利用相关的生态环境问题,提出制约周口市土地资源可持续利用的主要因素并分析原因。研究表明,高强度的土地开发活动给周口市带来诸多的生态环境问题,主要表现在四个方面,即生态退化、水生态平衡、生态多样性破坏、点源和面源污染。第四章从土地利用规模布局、基础设施建设和土地开发整理三个方面,分析研究土地利用与生态环境的关系,并借助生态环境脆弱性评价,定量分析周口市生态环境承载力。研究表明,周口市土地生态系统处在一个中度脆弱的平衡阶段,区域内现有生态系统趋于平衡,相对比较稳定。如果不改变传统的土地利用方式,继续对土地资源无限制地开发利用,生态环境的相对平衡将被打破,由于系统的自我恢复能力较差,生态系统将处于逆向演替之中,生态环境承载力将会大大降低。第五章提出了一系列协调周口市土地利用与生态环境关系的对策,包括建立生态环境适宜性分区和生态环境友好型的土地利用模式,并提出了相关分区的管制措施。论文的第六章在所做研究基础上,针对周口市土地利用与生态环境建设实际情况,提出统筹土地利用与生态环境建设的建议及措施。更多还原

【Abstract】 since entering the 21st century, the relationship between land use and ecological environment attract more and more attention., city construction changed a lot with the rapid economic development. Strongly demand for land had made far-reaching effects on land-use intensity、manner、scale and layout, what’s more, it strong shocks on the ecological environment, ecological security is facing serious threat. In order to ensure ecological security, achieve sustainable economic and social development, we must put the coordination of land use and ecological environment on the very prominent position. It puts forward a new requirement in how to protect the economic and social development in the demand for land and balance the environmental protection and ecological construction.This article takes Zhoukou city as an example and puts forward a series of measures ,in order to provide a scientific basis to construct land ecological security of the Zhoukou City and promote the sustainable development between land-use and ecological environment. This article including six chapters:Chapter I:discusses the background and the meaning of the research, overviews the process of the study on the relationship between land use and eco-environmental, Then put forward the contents、research methods and technical rout of this article. Chapter II :makes a overview to Zhoukou regional, mainly analyze the pHysical geograpHy, natural resources and social-economic development.Chapter III: provides the aspects and analyzes the reasons which influence the sustainable of the land use through analyze the status of the ecological environment and other related problems of Zhoukou. Studies shows that high intensity of land development activity brings about a lot of problem to Zhoukou’s eco-environmental ,mainly reflected in four aspects: ecological degradation, water ecological balance, biodiversity destruction, point source and non-point source pollution Chapter IV :analyzes the relationship between land use and ecological environment from the layout of the scale of land use、infrastructure construction and land exploitation and arrangement , then use the model of the eco-environmental vulnerability evaluation, quantitative analysis the capacity of the ecological environment of Zhoukou City. Studies show that the eco-systems of Zhoukou City land at a moderate stage, the eco-systems of Zhoukou City are relatively stable .If do not change the traditional patterns and continue to exploit land resources ,the relative balance between the ecological environment will be broken, because the system can not self-restore, ecosystems will be in reverse succession, the capability of the ecological environment will be greatly reduced.Chapter V :it provides a series of advice of how to coordinated the relationship between land use and the ecological environment, including how to establish the regionalization of feasible and ecological environment-friendly land use patterns, then put forward the measures of each reagion.Chapter VI : put forward the methods and measures of how to harmonize land use and ecological environment construction on the basis of the status of Zhoukou city.更多还原
