Abstract:Military historical geography that is the important research content of Historical geography is also one of the Military science. It is relate to three subjects system, which are Geographical science, Military science and History. The problem of defensive of Ancient capital had been concerned over in the research process of Military historical geography. As a capital city of country, not only is it the political and economic center of country, but also is the economic center. As the sometime, the capital is a sign of existence of country. So security will be the first element in the city. If there no security guarantees and other functions, it will be greatly threatened. From ancient times to the present, capital often is the core of a national defense system, and is the best focus of national defense strength and to improve the area of structure. Research the capital defense, Helps to know the national defense system, recognizing the City planning layout ideas, architecture and construction facilities, to meet the principle of site selection and other problems, and The relationship between man and geography in historical period.City of the tang dynasty is the largest invasion force in our history of a capital, It in the area of Guanzhong is the most capital construction Dynasty in our history and the longest history. There are so many dynasties and the government build the capital must have inherent law to follow. The research shows that one important reason is the characteristics of the region for defense of Guanzhong.Geographical shape is an important element in build capital military defense system. This article researched Chang'an city of military defense systems in the Tang Dynasty. Through the research tried to construction a research framework of capital military defense system.In the process, this article mainly from the following aspects:First, we discussed the military defense systems basic research in the framework. It include study the main contents, methods and so on. Military defense theory is an important hypothesis of civic origin. City defense system is based on the enemy's forces, the terrain and the conditions established, The city and its periphery adjacent regions consist of organization of the ground,force tabs,fire allocation system,obstacle construction,all kinds of security and etc. Military historical geo-analysis of defense system, it should include all kinds of defense elements in space configuration, rheological process. Military defense system constitutes elements include the material realm, both the political and spiritual realms. This paper applies documental, map method, confirming the archaeology materials and field investigation, system analysis, comparative method, spatial analyses, etc.Second, the concern of the military terms and conditions of terrain Tang Dynasty Chang an City defenses (second and third, fourth chapter. The results showing that in the periphery of the city of the conditions are conducive to the area of concern on three sides mountain, plateau, a block east of the yellow river and greatly increased the traffic problems. For a long time past, people build a lot of export where is the heat allowed to Guanzhong, and play the role of the security to protection guanzhong. The most important defensive barrier are the external conditions of terrain and defense place. Guanzhong plain was also constructed urban agglomeration and traffic network, this is contributed to troop movements of internal. But because of the wide plains, it is very difficult to defense. So they must to build urban agglomeration. In the area of concern Huazhou, Xianyang, Wugong, Fengxiang Fengtian and other cities to provide defense for Changan。Changan was the largest scale in the Tang Dynasty. But the defenses very pool of the city wall. Not give full scope to defence. The building of three imperial palace have a certain defenses facilities and resist an attack. In addition, the royal city and prohibited place has also a certain function of guarding against. Changan located in the central Tang Dynasty territory. During the early to middle stages of tang dynasty, Changan was within striking distance of the Regimes of Minority Nationality. In other words, as defend national frontier, it is the important supporting of Xibei defense.Third, the tang dynasty of the city of the defense case. (the fifth chapter) At all defensive factors, the human factor is the most important and decisive factor. in our army made a tremendous change in the city's defense forces has changed several times. early in the army, great-great-grandfather than drong continue to improve the government troops, in the area of concern to establish powerful army base of the concern raised by the four patterns. The same period, the city's defenses were mainly from the government and the soldiers to defend the city of sixteen. Great-great-grandfather period is also princely The same period, the city's defenses were mainly from the government and the soldiers to defend the city of sixteen. Great-great-grandfather period is also princely wait for the army is an unstable factors than drong be rescinded. the soldiers made to Xuan zong towards going to the dogs, the same period, a period of than drong Beira the army have been developed gradually for the defense of the city government to become the main body of soldiers, particularly in the defensive, mirage Beira played an important role.Wait for the army is an unstable factors than drong be rescinded. the soldiers made to xuanzong towards going to the dogs, the same period, a period of thandrong beiya the army have been developed gradually for the defence of the city government to become the main body of soldiers, particularly in the defensive, miyagi beiya played an important role. xuan zong period for the settlement of the demand for rapid development, fang Zhen, the city's defense forces continued weaken yasushi the rebels stormed in, all the chang an the Later Tang Dynasty emperors fled away. Pacify yasushi about the city of defence after the army was strengthened, and of god for the period for beiya after a long time for the lead to stability and security of the city has played an important role. When the power of strong, the city is gradually soldiers and eventually death. These are mainly in the city of defense forces of the eunuchs also played an omen, Beijing, wan nian and changan two counties are defense and security.Fourth, the city of the military logistics supply system in defensive operations, horses and weapons and equipment and food supplies of military logistics supply is also essential. The city where once our concern areas are important food production based. But as climate, the population, grain up system and government of the northwest field army and take food supply for many reasons and have a food crisis of several majors. Therefore, always will lead to some areas of concern for the existence of operation lifeline shall attach great importance to and had to build, dredging facilities. At the same time, to buy such concern, the city of supplementary food supply and its areas of concern for a few major cities of grain reserves; and base. The northwest area is the base of the city of supply, the cavalryman to develop more mature, the armies depend on the higher the area of concern in the pasture. The tang dynasties have built the city of the armory in tai chi palace, the emperor to the absolute control of arms and to imprisonment and the army.Fifth, this example about the city by the military defense system is for comment. This article in accordance with the national war, and suddenly turn into a15- kilometer-wide inside-Palace war, war and three forms for the mess, Jingyuan yasushi mutiny and dew of the same three which to show different circumstances, the city's defense system role, and its advantages and disadvantages. After the Han and the city, the period of Ming and Qing the city's defense system has more regard, the tang dynasty. the city of.By the above analysis, the paper established the city of the military defense of the basic features. its characteristics are these:A city's defenses, the tang dynasty formed layers, the out to is the third floor, a more prominent role; Second, the generation of the city of the external and internal threat to many changes happened, the changes were forced to focus on the defensive wall Tang Dynasty make new deployment; Third, generations have the defense of the city of the army made a great change and make changes in; Fourth, the tang dynasty pays great attention to the city of supplies and reserves.Through study, the preliminary establish a research on Chinese city in defense of the basic framework in this respect, will further explore and to build up an ancient city in china's military defense system, and this evolutionary process in the evolution of the relationship between the exploration of land.
