论文依据土地提供主要服务的差异将土地利用功能划分为3 个大类和6 个亚类；通过对比研究区2010 年与2020 年土地利用类型变化和土地功能的变化，分析两者表征土地系统变化的差异；再利用5 个景观格局指数对比分析土地利用类型变化和土地功能类型变化对景观的影响，探索两者表征景观的差异。通过上述分析得出如下结论：①土地利用类型与土地功能类型均能表征不同类型间的转化，但前者可更为细致地表达出土地功能所包含土地类型间的转化；②在土地利用类型不发生变化的情况下，土地功能依然可以表征土地系统的变化；③土地功能变化分析能得到更为宏观的景观空间特征。

The focus of the study is to reveal the land use system change by the change of land use function. Attempts have been made to quantify land functions based on land use information which are often limited since land use is not always a good indicator for the actual functions performed by the land at that location. According to the difference of providing services by the land, the land use function is divided into three categories and six types in this paper. Compared to the result of land use change and the effect on the landscape pattern, several conclusions of differences by using land use function were drawn: 1) Both land use types and land use functions can reveal the change among the different types of both. The land use types can reveal the change among the differenct types making up the special land use functions more clearly. Meanwhile，this indicated that land use function can maintain the same with the dramatic land use types'change too. 2) The land use function may dramatically change without any change in land use types, this indicated that impact assessments based on current monitoring and modeling techniques are often limited to land functions. 3) The analysis on the land use function may give a more comprehensive result of land use system than the result of land use change under the combination of special land use types. The analysis result by using land use function is not the simple sum of the result by the land use types composing the special land use function. The analysis of land use change's effect on the land use system may only show the effect of a special land use type, while the analysis of land use function on the land use system not only provide the information of the effect of the special land use type, but also the integrated effect among different land use types.
