北宋与西夏的对峙及其对陕北生态环境的影响

北宋与西夏在陕北一线剑拔弩张,长期对峙,双方在这一线驻有大量部队,并断断续续进行了几十年的战争,民族关系几度紧张。为了备战,北宋与西夏都动员了大量的人力在沿边修筑了大量的军事设施,屯田驻守,客观上加强了对陕北的规模开发。局部地区的过度开发对陕北的生态环境产生了重大影响,自然植被遭到严重破坏,大片草地和林地被开垦,土地沙化和水流失的速度大大加快,生态环境出现恶化趋势。

The Confrontation Between Xixia and the Northern Song Dynasty and Its Impact on the Ecological Environment in Northern Shaanxi

Xixia was at loggerheads with the Northern Song Dynasty in the front in Northern Shaanxi,and the confrontation lasted for long,with large troops stationed on the front.The wars between them went on for decades with several occasional breaks,which greatly influenced the ethnic relations.To prepare for wars,both the Northern Song Dynasty and Xixia mobilized a lot of manpower at the border to build a large number of military installations and stationed troops,which objectively strengthened the development of Northern Shaanxi on a large scale.The over-development in some areas of Northern Shaanxi had a significant impact on the ecological environment and natural vegetation was seriously damaged;large areas of grassland and woodland had been cleared of.As a result,land desertification and the loss of water became more and more serious at a fast rate,which led to the trend of deterioration of the ecological environment.
