Classification and Spatial Pattern of Rural Multifunction from the Diversify of Construction Land Use:Taking Tongshan District of Jiangsu Province as a Case Study

The development of rural area in suburban(RAS)is comprehensively influenced by the mixed processes of non-farming,local urbanization and rural industrialization and has distinctive multifunctional features on the socioeconomic and resource utilization.Multifunctional reconstruction in the RAS is mainly manifested by changes in the quantity and structure of the construction land use(CLU).We took Tongshan District of Jiangsu Province as the study case.Following the logic of identifying,clustering,and diagnosing,we assessed the functional features of CLU and analyzed the differentiation of the scale and structure of CLU in RAS,with the aim of identifying the types and characteristics of multifunctional development in these regions.This study found that:1)typical RAS were experiencing multifunctional space reconstruction,and their multifunctional value was emerging and highlighted.The CLU was rapidly expanding,and the types of CLU were evolving from single to multiple uses;2)based on the dominant function of diverse rural CLU,we classified RAS into five types,dominated by the following functions,respectively:commercial services,industrial production,residential living,basic support and public service;3)according to the dominant function and spatial pattern,the development types of RAS were classified into agricultural service,comprehensive services,and integrated industries service,showing a circular spatial pattern from the suburbs to distant suburbs.The results can provide policy implication by creating new development impetus from rural multifunction perspective to promote the RAS revitalization.

A Constructive Use of ChatGPT in the Classroom:An Empirical Study

ChatGPT,launched on November 30,2022,has been adopted by the industries and academia alike.Students have started using ChatGPT for classroom assignments.In the search for the use of this tool for constructive purposes,the professor of a graduate class(MBA)on Supply Chain and Operations Management decided to require students to use ChatGPT to first generate some material for their term papers.Typically,ChatGPT generates one to two pages of original material for the student who is not well trained in using it,which was the case for the students in this class.Then,the students were asked to use the ChatGPT-generated material as a guide to writing a 10-page long paper with new references and citations added.A comparative study is conducted to determine the usefulness of ChatGPT on this project.The preliminary results indicate that students found ChatGPT useful in generating their own papers.Meanwhile,our analysis shows beginners of ChatGPT have limited capacity to generate high-quality content based on ChatGPT.Also,text mining is conducted to compare the readability and information density of ChatGPT-generated content and student-generated content.

Spatial expansion and potential of construction land use in the Yangtze River Delta

Based on remote sensing data of the Yangtze River Delta(YRD) in the years of 1991, 2001 and 2008, the paper built an index system of land use potential restraint factors in YRD, according to geological condition, terrain condition, water area, natural reserve area and basic farmland, and evaluated construction land potential based on the platform of GIS spatial analysis model. The results showed that:(1) the construction land increased rapidly since 1991 and reached 24,951.21 km2 in 2008, or 21.27% of the total area. Among all the cities in the YRD, Shanghai took the greatest percentage, followed by Jiangsu and Zhejiang. Spatially, areas where government departments are located became the growth center of construction land. Prefecture-level cities were the fastest growth region and the changing trend showed circle layered characteristics and significant increase with Shanghai and Suzhou as the core.(2) The higher the quality of construction land potentials(CLP), the smaller the number of CLP units. High sensitive area accounted for the largest percentage(40.14%) among all types of constraint regions and this was followed by medium sensitive region(31.53%) of the whole region.(3) The comprehensive CLP in the YRD was 24,989.65 km2, or 21.76% of the total YRD. The land use potential showed spatial distribution imbalance. CLP of Zhejiang was obviously larger than that of Jiangsu. CLP was insufficient in regional central city. Moreover, CLP in the YRD formed a circle layered spatial pattern that increasingly expanded centered in prefecture-level cities. Low potential area expanded from north to south. High potential area was mainly located in south YRD. Areas with zero potential in the YRD formed a northwest-southeast "Y-shaped" spatial pattern in north Hangzhou Bay.(4) CLP per capita in YRD was 0.045 ha/person and also unevenly distributed. Some 25.57% of the study units at county level nearly had no construction land and 8.24% of the units had CLP per capita below the national average level. CLP per capita in less than 25% of the county-level units was larger than the YRD average level, which were mainly located in Zhejiang. Therefore, research on the construction potential area in YRD was favorable for analysis of the development status and potential space of this region under the background of rapid urbanization and industrialization.

Temporal-spatial Characteristics of the Urbanization of Rural Land in Xinjiang

Relying on remote sensor technology, GIS and Land--sat TM digital images,the authors use spatial and statistical analysis to examine the temporal-spatial characteristics of the change caused by urban construction in Xinjiang’s rural areas from the end of the 1980s to the end of the 1990s. The primary findings show the following: 1) The urban construction in rural areas has increased drastically. The expansion speed of urban land use has accelerated over the past decade. The sub-land use changes caused by the urbanization of rural are characterized by salient regional differentiation among the three main regions and among the 85 counties of Xinjiang. 2) The shift of land use is mostly characterized by cultivated land and grassland being used for urban and industrial projects. Moreover, this change of land use is characteristic of regional differences. 3) Factors of rural-urban construction land use changes in Xinjiang, are undoubtedly affected by natural environment, social, economic conditions, and to a larger degree by population growth, GDP development and industrial development..

A Web-Based CAL System Constructing Tool Using Case-BasedReasoning Approach

It seems that a big problem in applying the WWW to education fields is that teachershave difficulty directly developing and managing a web-based intelligent CAL (Computer AidedLearning) system, because of the shortage of funds and teachers who are skilled in both AI (ArtificialIntelligence) and computer information technologies. Focusing on solving the problems we havedeveloped a general-purpose tool called WWW-CALIST (WWW-based Computer Aided LearningIndividual-adaptive System Tool), which helps teachers build up a web-based individualized adaptivecomputer aided learning environment called 'test→search for information using an adaptivekowledge map→adaptive learning'. By using easy-to-use interfaces equipped with the tool, ateacher who knows only the HTML can develop and manage web-based individualized adaptive CAIsystems for various education domains.
