摘要
建设用地适宜性评价是城镇规划布局的基础,为城镇用地提供参考和依据.评价过程中,评价因子的选择、指标体系的构建和权重的设定最为关键,是各类土地适宜性评价的根本差别.建设用地适宜性评价对土地质量的要求主要是地形和地质条件.我国近年大量开展的建设用地适宜性评价呈现以下特点:评价尺度以县市为主,并呈变小趋势;研究重点由平原转向山地,更加注重生态;新的评价模型、分析方法、研究视角不断出现,多因素综合叠加模型得到最广泛应用;评价因子的选取和权重的确定多采用德尔菲法和层次分析法;GIS广泛用于评价中,提高了评价的效率和精度.总之,建设用地适宜性评价的研究越来越成熟,理论和方法不断得到丰富和发展.
Evaluation of construction land suitability is the base of urban planning layout,providing reference and basis for land use.The choice of evaluation factors,the construction of index system and the weight configuration are the key to evaluation,distinguishing it from other kinds of evaluation.The land quality requirements of construction land suitability evaluation focuses on topography and geology conditions.A great deal of construction land suitability evaluation has been done in recent years in China.Such evaluations have the following features.The county scale predominates such evaluations and the scale tends to become even smaller.Research emphasis shifts from plain to mountain areas with more attention paid to ecology.New evaluation model,analysis method and perspective of research constantly emerge,multi-factors are widely applied.The Delphi method and the analytic hierarchy process(AHP)are mostly used to determine the evaluation factors and weights.widespread use of GIS improves the efficiency and accuracy of evaluation.All in all,the evaluation of construction land suitability is more and more mature with enrichment and development of theories and methods.
