中文摘要：
通过对土地资源承载力的凋研，系统地阐述了土地资源承载力定义，分类汇总了土地资源承载力的国内外研究进展及研究方法模型。其计算方法可归纳为4大类：基于“人口一土地一经济”结构的计算模型、基于土地生产潜力模型、趋势外推法模型和生态足迹法模型，从模型计算方法、模型的应用以及优缺点等进行了分析。目前土地资源承载力的概念和内涵尚未达到统一，模型方法也没有固定形式，数据资料获取手段滞后，影响了评价结果。从土地资源承载力研究发展趋势看，其研究方向趋于综合性，研究空间范围趋于多样性；研究方法上，现代技术如遥感、地理信息系统、全球定位系统等的作用日趋突出；在大数据时代必须要逐步建立土地资源信息数据库，才能提高土地资源承载力计算结果的准确性和时效性。
英文摘要：
The investigation of the land carrying capacity systematically explains the definition of the land carry-ing capacity,and summarizes its classification and the model of research methods at home and abroad.The cal-culation methods can be summarized as four categories,based on the model of Population -Land -Economy structure,the model of land productivity potential,trend extrapolation model and ecological footprint model. The above models are analyzed through the calculation methods,the applications and the advantages and disad-vantages.Nowadays,the concept of land carrying capacity is not unified.Moreover,the models vary from one case to another.In addition,the data acquisitions lag behind,and influences evaluation result.The land carry-ing capacity development tends to be comprehensive and diversity.Modern technologies,such as RS,GIS and GPS,have played an important role.In the era of data,it must gradually establish information database of land resources to improve the accuracy and effectiveness.
