类型理论

Generally, Toft's"strategic interaction"is relatively new and explanative. Being an important starting point for this research, Toft's"strategic interaction"perspective still leaves us with some questions: Firstly, Toft's analysis on the four types of strategy is too far-fetched; Secondly, Toft deliberately evades the question of a strategic choice in his theoretical model; thirdly, the argument"time is conducive to the weak rather than the strong side"is not convincing.

总体上看，托夫特的"战略互动论"比较新颖且有相当的解释力，因此也构成了本研究的重要起点，但它也还是给我们留下了几点重要的疑问：首先，托夫特关于四种战略类型划分过于牵强；其次，在其理论模型中，托夫特有意地回避了战略选择的问题；再次，关于"时间有利于弱者而不利于强者"的逻辑解释也并不能令人信服。

After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.
