| 石家庄市土地生态安全评价研究 摘 要 随着社会的不断发展，地球的生态安全受到越来越大的挑战，土地资源和生态环境受到越来越多的破坏。地球环境安全研究是可持续陆地研究的极限，具有理论和实践意义。以地理生态学理论为基础，结合国内外相关研究动态和成果，结合石家庄市的特点，建立一套地球生态安全评价指标体系，采用均方误差决策法和德尔菲法计算权重并进行科学修正，然后计算结果对石家庄市各县的6588份分析结果表明，石家庄市的生态安全不容乐观。在考虑石家庄土地生态安全现状时，该区域的土壤特征是，将该区域划分为第一山地生态建筑区和东部生态建筑区，并根据影响两个区域生态安全的各种因素，相应的对策和建议已经取得进展，以实现该地区的生态安全。 关键词：土地生态安全；石家庄；均方差决策法 Abstract With the continuous development of society, the earth's ecological security is facing more and more challenges, land resources and ecological environment are more and more damaged. The research of earth environmental security is the limit of sustainable land research, which has theoretical and practical significance. Based on the theory of geoecology, combined with the relevant research trends and achievements at home and abroad, combined with the characteristics of Shijiazhuang City, a set of evaluation index system of earth ecological security is established. The mean square error decision-making method and Delphi method are used to calculate the weight and make scientific correction, and then the calculation results are analyzed for 6588 counties in Shijiazhuang city. The results show that the ecological security of Shijiazhuang city is not optimistic . Considering the current situation of land ecological security in Shijiazhuang, the soil characteristics of the region are that the region is divided into the first mountain ecological building area and the eastern ecological building area. According to the various factors affecting the ecological security of the two regions, the corresponding countermeasures and suggestions have made progress to achieve the ecological security of the region.
