In the new era of building a socialist modernization country with the goal of promoting high-quality development,we deeply analyze the knowledge system of the Introduction to Architecture course.This analysis is based on the cross-disciplinary specialties of local applied universities and the orientation of prioritizing employment and integrating industry and education.We propose the teaching reform of“theory-practice alternation”which is adapted to the current times and societal needs.Finally,we comprehensively summarize the effectiveness of curriculum construction,in order to provide theoretical references for the implementation of fostering character and civic virtue and deepening the reform of collaborative education mechanisms. 展开更多

[ Objective] The research aimed to analyze temporal-spatial distribution and change trend of the temperature in Beibei District. [ Method] Based on temperature observation data at 6 ground meteorological observatories of Beibei District from 1951 to 2010, EOF and linear trend method were used to analyze temporal-spatial distribution and change characteristics of the temperature in Beibei District in recent 60 years. [ Result] Tem- perature in Beibei District in recent 60 years overall presented rise trend, and average rise velocity was 0.045 ~C/10 a. Temperature rise in autumn was the most obvious, while summer temperature presented decline trend. Average temperature presented gradual rise trend from January to July and gradual decrease trend from August to December. Seen from spatial distribution, temperature in the whole district was higher in the west and lower in the middle. Abnormal spatial distribution of the average temperature in the whole district mainly had consistent higher (lower) type, south- north reverse type and east-west reverse type.

Mountain area is an important geographical unit of land,and its ecology is sensitive and fragile.Over the past few decades,human activities have caused dramatic changes in land use in mountainous areas,which caused changes in landscape patterns and impacts on the ecological environment.It is unknown how the mechanism of land use affects the landscape pattern at different scales.The Hantai District,a typical human settlement in the mountain area in Shaanxi,China,was chosen as the study area.Based on the remote sensing images,the mathematical models and landscape indexes were adopted to evaluate the impact of land use change from 1998 to 2017 on the landscape pattern at different scales,and its main driving forces were analyzed.The results showed that the urbanized land expanded largest from 15.39%to 24.30%,and cultivated land experienced the largest decline from 43.54%to 35.35%.Changes in land use have made the patch morphology of most land types developed from a natural random to a sawtooth shape,and its spatial pattern evolved from a ruleset to a fragmented expansion.This reflects the continuous strengthening of human intervention in the process of regional development.Under the jurisdiction of Hantai District,the biggest change in landscape pattern is in Hanzhong City and Qili Town.The improved economy and increasing population and urbanization rate were the main factors that cause these changes.This research could provide necessary information for understanding the evolution mechanism of land resources in mountainous human settlements for mountainous areas with significant geomorphic differentiation. 展开更多

[Objective] The research aimed to study the influence of climate warming on the agriculture in Shenbei New District of Shenyang in recent 38 years.[Method] Based on the temperature data in Shenbei New District of Shenyang during 1971-2008,by using the conventional statistical method,the variation trends of temperature and active accumulated temperature in Shenbei New District under the climate warming environment were analyzed,and the influence of climate warming on the agriculture was discussed.[Result] The annual average temperature,annual average maximum temperature,annual averageminimum temperature and ≥ 0℃,≥ 10℃ active accumulated temperatures which were passed stably in Shenbei New District in recent 38 years all showed the obvious rising trend.The climate tendency rates were respectively 0.4,0.3,0.1℃/10 a and 79.1,76.7℃·d/10 a.They all showed the declining trend in the coldest December,January and the rising trend in other months.The rising range of maximum temperature was bigger than that ofminimum temperature,and the rising range in summer was bigger than that in winter.The analysis result was different from that of many scholars.When the temperatures rose,and the heat resources increased,the agricultural cropping index improved,and the cultivated boundary of mid-late maturity variety moved northward.The industrialized agriculture developed quickly.Meanwhile,the risks of drought and flood disasters increased,and the insect pest aggravated.[Conclusion] The research provided the scientific basis for improving the cognizance about the influence of climate warming on the agricultural production and strengthening the strain capacity of local agricultural production adapting the climate variation. 展开更多

Administrative division is an important means of political power reorganization and management,resource integration and optimal allocation,which profoundly shapes the spatial layout of urban development in China.To clarify and compare differences between counties,county-level cities and municipal districts is the primary premise for the study of administrative division and urban development.This paper analyzes the institutional differences between counties and county-level cities,as well as counties,county-level cities and municipal districts,from the aspects of organizational structure,urban construction planning,land management,finance,taxation and public services.The research shows that the establishment of counties,county-level cities and municipal districts adapt to different levels and stages of economic and social development,and the conversion from county to county-level city and the conversion from county(or county-level city)to municipal district are both important transformation ways to change their administrative systems,which has different management system and operation pattern.At the same time,the transformation of county-level administrative region is also a“double-edged sword”,we should think about the administrative system as a whole to decide whether it should be adjusted,and effectively respond to the actual needs of local economic and social development. 展开更多

The year 2019 marks the seventh anniversary of Shinzo Abe's return to office,alongside the administration's obsession with Constitutional amendment.During the 25th House of Councillors selection in July,Prime Minister Abe changed the rules applied for the four national elections in 2012,wrote the Self-Defense Forces into the Constitution and the Liberal Democratic Party(LDP)convention,and deliberately made the amendment a focal point of controversy in his election campaign.However,when the results of the election came out,the pro-amendment forces,with the LDP at their core,didn't reach the two-thirds majority threshold required for Constitutional revision.Going forwards,the Abe-led Liberal Democratic Party will strive to consolidate Constitutional amendment forces in the National Diet,hoping to cross the majority threshold,and at the same time to coerce opposition parties to comply with passing LDP draft revisions to the Constitution in the National Diet as soon as possible,in order to submit these to national referendum.In the meantime,preparatory works for this referendum are being carried out through the use of political resources to mobilize public support.Whether Abe can reach the political objective of Constitutional amendment during his current term of office and how the Constitutional issue in Japan will play out is sure to attract global attention. 展开更多
