摘　　要：耕地后备资源是落实耕地占补平衡的重要保障。新疆地处中国西北内陆,土地开发程度较低,是中国耕地后备资源集中分布区,开发利用潜力巨大。根据新疆的实际情况,采用主成分分析法与耦合模型探究新疆耕地后备资源和生态环境之间的耦合程度与影响机制。结果表明:新疆耕地后备资源分布具有显著的空间差异,各地州生态环境指数整体偏低,大部分耕地后备资源分布地区属于中、重度失调发展类型。昌吉、阿勒泰、塔城地区耦合程度较好。针对新疆特殊的地域类型和巨大的生态压力,提出在开发前要重点评估资源开发对当地生态的影响等建议。The reserve resource of cultivated land is an important guarantee for the implementation of the balance of cultivated land occupation and compensation.Xinjiang is located in the inland of northwest China,with a relatively lower level of land development.It is the main district where China s cultivated land reserve resources are concentrated.Its utilization potential is huge.According to the actual situation in Xinjiang,the principal component analysis method and the coupled model were used to explore the coupling degree and influence mechanism between the cultivated land reserve resources and the ecological environment.The results showed that there was a significant spatial difference in the distribution of cultivated land reserve resources in Xinjiang.The ecological environment index of each region was generally low.Most of the cultivated land reserve resources were classified into medium and severe imbalance development types.Changji,Altay and Tacheng regions had better coupling degree.Finally,according to the special geographical types and huge ecological pressures in Xinjiang,it was proposed to evaluate the impact of resource development on local ecology first before development.
