党的十九大报告提出加强黄河治理，并将黄河流域的发展上升为国家战略。 宁夏作为我国西部重要的生态屏障的重要组成部分，在维护国家安全以及生态安 全战略格局中具有重要的地位。 论文基于生态安全理论体系，以宁夏 18 个县域为研究对象，选取 2002-2017 年为研究的时间段，基于宁夏目前的生态环境现状建立涉及生态安全现状和生态 安全保障状况两方面的评价体系，一方面基于能值生态足迹理论评价宁夏目前的 生态安全状况。另一方面建立宁夏生态安全保障体系，运用客观赋权确定指标的 最终权重，然后利用 TOPSIS 法求出宁夏生态安全保障度指数，并在分析的过程 中运用 GIS 空间分析、趋势分析以及克里格空间插值的方法从时间和空间两个维 度来分析宁夏的生态安全和保障状况，最后又运用面板回归模型，深入分析各县 域生态状况与保障度之间的关系，为其宁夏生态文明建设提供参考。

The report of the 19th National Congress of the Communist Party of China put forward to strengthen the management and protection of the Yellow River and raise the development of the Yellow River basin to a national strategy. Ningxia, as an important part of the ecological barrier in the west of China, plays an important role in maintaining national security and the strategic pattern of ecological security. Therefore, based on the theoretical system of ecological security, this paper takes 18 counties of Ningxia as the research object, selects 2000-2017 as the research period, Based on the current situation of Ningxia's ecological environment, an evaluation system involving the current situation of ecological security and ecological security is established, On the one hand, based on the emergy ecological footprint theory to evaluate the current situation of ecological security in Ningxia, On the other hand, establish the ecological security system of Ningxia, and determine the final weight of the index by objective weighting, and then calculate the ecological security index of Ningxia by TOPSIS method, In the process of analysis, GIS spatial analysis, trend analysis and Kriging spatial interpolation are used to analyze the ecological security and guarantee of Ningxia from two dimensions of time and space, Finally, the panel regression model is used to analyze the relationship between the ecological status and the degree of security, so as to provide the basis for the construction of ecological civilization in Ningxia.
