Conclusions on the Implementation of Regulation of the National Significant Seismic Monitoring and Protection Regions from 1996 to 2012 in the Chinese Mainland

The regulation of the National Significant Seismic Monitoring and Protection Regions(NSSMPR for short) is defined by the Law of the Peoples Republic of China on Protecting Against and Mitigating Earthquake Disasters.The first stage of implementation of the regulation of NSSMPR in the Chinese mainland was finished from 1996 to 2005.The second stage is being carried on from 2006 to 2020.With the support of the National Social Science Foundation,this paper follows up and evaluates the implementation of the regulation of NSSMPR from 1996 to 2012 in the Chinese mainland.Based on analysis of earthquake examples and investigation data,we find that the effect of disaster mitigation is good,and on this basis,some suggestions are proposed to improve the regulation of NSSMPR.

Evaluation of yield,stability and adaptability of national winter rapeseed regional trials in the upper Yangtze River region in 2017-2018

Rapeseed variety needs to be tested by regional trial in multiple sites for many years before being applied in market in China.Performants of rapeseed were affected by the interaction of sites and varieties.Evaluation of regional trials is very important for guiding rapeseed breeding.GGE(genotype main effects and genotypeenvironment interaction)biplot was used to evaluate yield,stability,adaptability,representativeness and discrimination of national winter rapeseed trials in the upper reaches of Yangtze River in 2017-2018.Results showed that the main effects of genotype(G),environment(E)and genotypeenvironment interaction(GE)were significant(P<0.01)for yield.Among them,E accounted for 46.95%total variation on average,G and GE accounted for 19.34%and 33.71%respectively.Eight varieties were found with high-yield,excellent stability and adaptability,including‘Yiyou 29’,‘Xiwang 920’,‘Liyouza 108’,‘Nanyou 546’,‘Dadi 195’,‘Jiayou 1’,‘Huayouza 28’and‘Yuhua 2’.Test sites included Nanchong,Mianyang,Wanzhou,Shuangliu and Chengdu in Sichuan Province and Zunyi together with Guiyang in Guizhou Province were selected for their excellent representativeness and discrimination.These results would provide theoretical basis for rapeseed breeding.

Review and Prospects on Rice Breeding and Extension in China

A large number of new varieties, especially hybrid rice, have been developed and released in China since 1998. The yield potential and grain quality of hybrid rice have also been improved significantly both for three-line and two-line hybrid rice including indica and japonica types as well. The trends on extension of rice varieties in China since 1986 has been marked by the increasing number of new varieties, decreasing annual planting area per variety, decreasing number of varieties with a large-scale extension area, while both the renewal rate and the proportion of core varieties with cross-provincial extension have remained unchanged. This current major problems and future goals of rice breeding and extension in China were also discussed.

Instruments of Urban Planning in Algerian City： Reality and Challenges

The year 1990 marks a line of rupture in the history of Algeria in general by the fundamental changes that have occurred, especially in the fields of urbanism and the land use planning, which has an important impact on space of the city and its environment. However, the absence of directives based on the reality of upstream territories and sometimes the conflict and the weakness of the instruments created at different levels： national, regional and local, have accelerated the galloping development of urbanization （the irrational consumption of land reserves inside and around the city）, often at the expense of the agricultural land. On the other hand, the involvement of new actors in the production of the framework built in the Algerian town was made without compliance with the rules of architecture and urbanism contained in the build permit and in the MPU （Master Plan of Land Use and Urbanism） and the SOP （Soil Occupation Plan） approved. The analyses conducted in the cities such as the capital Algiers and Setif illustrate this situation well. This article presents these situations of paradox, identifies their causes and suggests the recommendations to implement in the framework of studies and actions to take, to correct and regulate their mutations.

Regional Tax Reform Goes National

China plans to increase resource tax to curb waste,but the plans raise fears of inflation After a year of experimental reform on the resource tax ratio in China’s western Xinjiang Uygur Autonomous Region,the State Council announced on September 21 to add the method of levying the resource tax ratio by value to the existing practice of levying the ratio by volume only.

MEMBER PRIVILEGES——Each of the Shanghai Cooperation Organization members finds its own national interests served within the regional organization

Facing common security threats, leaders of six countries-Russia, China, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan-established the Shanghai Cooperation Organization in June 2001 to maintain regional stability and security, fight terrorism and extremism, prevent conflicts and enhance economic cooperation. The SCO's primary goals are economic cooperation and fighting terrorism.

Analysis and Numerical Simulations of the Teleconnection Between Indian Summer Monsoon and Precipitation in North China

In the early 1980s, Chinese meteorologists discovered the positive correlation in summer rainfall between India and North China and the correlation was later confirmed by some researches in and outside China. Based on a variety of meteorological data from 1951 to 2005 and numerical simulations, the present study investigates such a correlation between Indian summer monsoon （ISM） and precipitation in North China. Furthermore, we discuss the intrinsic relations of the positive （Northwest India）-negative （the Tibetan Plateau）-positive （North China） precipitation anomaly teleconnection pattern from two aspects of thermal and dynamical factors, which not only confirms the precipitation teleconnection previously discovered again, but also reveals the influence mechanism of the ISM on the rainfall in North China. The results show that： （1） When the ISM is strong （weak）, the precipitation in North China tends to be more （less） than normal; however, when the rainfall in North China is more （less） than normal, the probability of the strengthening （weakening） of the ISM is relatively lower. This implies that the ISM anomaly has more impact on the rainfall in North China. （2） The Indian low usually dominantly impacts the intensity of the ISM. When the Indian low deepens, the low troughs in mid-high latitudes are frequently strengthened, and the ridge of the western Pacific subtropical high （WPSH） extends westward. The southwesterly water vapor transport originated from low-latitudes and the southeasterly water vapor transport along the southwestern flank of the WPSH converge in North China, which is favorable for more rainfall there than normal, and vice versa. （3） The simulations from the regional climate model developed by National Climate Center （ReGCM_NCC） capture the salient feature of the precipitation teleconnection between India and North China. The simulated anomalous atmospheric existence of such a teleconnection from another circulations are close to observations, which confirms the angle.

Wang Yong,Ten Lectures on Cultural Circulation in East Asia

Nowadays,world history and national/regional history studies in China focus on countries along“the Belt and the Road.”With an eye on both the reality and the populace,Wang Yong combines historical research with practical concern in his new work Ten Lectures on Cultural Circulation in East Asia,expanding the academic horizon.
