The Conflicts in the Western Regions of China, Made by Turgesh, Arabs and Tibetans, in the Early Tang Dynasty

开元时期是西域形势趋于复杂的关键时期。只有理清了此时期唐、吐蕃、大食与突骑施在西域斗争的脉络和纲要,才能更好地把握各方势力对西域争夺的实质。通过中外史料及研究成果的结合,对唐朝与突骑施、大食与突骑施、唐与吐蕃在此时期对西域的争夺进行了考察,认为突骑施对大食东侵的抵御的内部原因在于其试图接替原来西突厥对西域的宗主地位的意愿;吐蕃最终能主导西域局势不仅在于自身军事力量的强大和唐朝的衰落,更在于其能围绕进入西域这一中心而灵活改变作战方略,从多方寻求突破。
