[目的]通过研究宁夏自治区青铜峡市的土地生态安全发展状况,为该市的土地生态安全及其可持续发展提供科学的参考依据。[方法]综合运用熵权法、P-S-R模型、综合指数法、地理探测器和GM (1,1)预测模型等方法对该区域土地生态安全、安全等级以及影响土地生态安全的主要因子进行评价研究,并对其未来9 a的土地生态安全状况进行预测。[结果]①青铜峡市土地生态安全综合指数在研究期间整体呈现出先下降后上升的变化趋势。2006-2009年土地生态安全指数呈现波动下降的态势,由2006年的0.446 3下降到2009年的0.419 1;2009-2016年青铜峡市土地生态安全综合评价值不断上升,由2009年的0.419上升到2016年的0.505 1,其安全等级始终保持为临界安全,研究期间青铜峡市土地生态安全整体水平不断提高和改善。②通过地理探测器诊断得出人口密度、农用化肥使用量、废水排放量、万元GDP能耗、工业固体废物产生量、建成区绿化覆盖率、水利、环保设施投资占GDP的比率等要素是青铜峡市土地生态安全的主要影响因素。③利用GM (1,1)预测模型对青铜峡市未来9 a土地生态安全发展水平进行预测,结果表明2017-2025年该区域土地生态安全水平不断上升,但其安全等级不高,仍处于临界状态,有待于提高和改善。[结论]研究期间青铜峡市土地生态安全波动变化明显,但总体上呈上升趋势,土地生态安全得到明显提升和改善。
[Objective] To reveal the status of land ecological security development in Qingtongxia City
and to provide scientific reference for land ecological security and its sustainable development in Qingtongxia City.[Methods] The land ecological security
safety grade and the main factors affecting the ecological security of the land were evaluated by using entropy weight method
PSR model
comprehensive index method
geography detector and the GM (1
1) forecasting model. And the land ecological condition in the next nine years was predicted.[Results] ① The comprehensive index of land ecological security in Qingtongxia City showed a rising trend after an initial decline during the study period. The land eco-safety index declined from 0.446 3 in 2006 to 0.419 1 in 2009 and the value of comprehensive evaluation of land ecological security in Qingtongxia City from 2009 to 2016 increased continually
it was 0.419 1 in 2009 and 0.505 1 in 2016. Though
its safety level varied around the critical safety
the overall level of land ecological security in Qingtongxia City was getting improved. ② Factors
including population density
amount of agricultural fertilizer used
amount of waste water
energy consumption per 10 000 yuan
amount of industrial solid waste generated
greening coverage of the built area
ratio of water conservancy and environmental protection facilities to GDP
etc. were determined as the main influencing factors of land ecological security in Qingtong Gorge. ③ The GM (1
1) forecast model was used to predict the level of ecological security development in the next nine years. The results showed that the level of land ecological security in the region would increase from 2017 to 2025
but the safety level is not high enough and still in the critical state
it need to be improved.[Conclusion] During the study period
the ecological security of Qingtongxia City changed obviously
but the trend was generally rise. The ecological security of land was obviously improved.
