【摘要】 土地资源是人类赖以生存和发展的物质基础,随着生产力的提高和人口的增加,人类对土地的不合理的利用和对自然的过度索取,造成土地退化,环境质量下降,从而使人类的生存和可持续发展受到严重影响。土地退化既有自然因素的影响,也有人为因素的影响,在自然因素中,地质环境条件对土地利用方式和土地利用格局的影响十分明显。本文依据地质条件对土地利用格局影响的理论,在明确地质环境的涵义,论述地质环境对土地利用格局影响作用的基础上,全面分析了呼和浩特市地质条件特征和土地利用现状,运用地理信息系统软件(MapInfo GIS、Map GIS)作出相关图件,对地质环境与土地利用间的相关关系进行初步的探讨,简要论述了呼和浩特市地质环境对土地利用格局的影响。通过初步的研究发现呼和浩特市的岩性、地形地貌、水文条件、地质构造等地质条件对土地利用的影响主要表现在:岩性和矿物成分决定了土壤的性质、机械组成,进而影响土地利用类型、天然植物类型和农作物种植种类;地形地貌在宏观上控制着城市布局和土地利用的程度和方式;水文条件影响农用地的分布以及作物的种类;地质构造影响城市(镇)的布局与建设。根据地质环境对土地利用的影响关系分析,提出呼和浩特市应对农业牧业用地、城市(镇)建设用地作出适当的调整;采取工程措施与生物措施,保护当地的土地资源与水资源。更多还原

【Abstract】 Land resource is a material base on which human beings rely on existing and developing. With productivity improving, population increasing and human being unreasonable making use of land and excess obtaining from nature, it brings about the land degeneration and environmental quality coming down. Therefore, there is a grave effect on live and development of human being. Factors resulting in land degeneration includes both natural factors and human factors. Geological environment condition has an obvious effect on land use way and land use pattern in natural factors.According to theory that geological condition has an effect on land use pattern and the implication that geological environment is made clear, the geological condition characteristic and land use current situation in Huhhot City were analyzed all round, the geographic information system software (MapInfo GIS、Map GIS) was applied to make the relevance map document and relation between geological environment and land use pattern was discussed. And the impact of the geological environment on land use pattern of Huhhot City was discussed briefly.By preliminary investigating of the condition it was found that the effect of lithology, landscape, hydrology condition, geological structure on land use of Huhhot City were as follows:The characters of soil depended on lithology and mineral components and effect land use types, natural plant types and crops to cultivate further; terrain and physiognomy controlled the city layout and the degree and way of land use on macroscopic view; farm-oriented distribution and the crop kinds was affected by hydrology condition; geological structure affected city (town) layout and construction.Base on analyzing relation in the impact of geological environment on land use, appropriate adjustment of land for agriculture husbandry and city (town) to build in Huhhot City and adopting project measures and living things measures to protect local land resources and water resource were put forward.更多还原
