为了找出对煤矿区生态安全影响较大的因素，以压力-状态-响应模型作为框架，选取17个指标构建了初步的指标体系，然后利用结构方程模型和湖北赤壁两个煤矿的调研数据，计算出指标的权重并评估出模型整体拟合性，确定最终的评价指标体系。结果表明，各指标的权重中，对生态安全压力、生态安全状态和生态安全响应影响最大的因素分别是工业三废负荷压力、水体（源）污染和人均工业总产值，且模型整体拟合性良好。
為瞭找齣對煤礦區生態安全影響較大的因素，以壓力-狀態-響應模型作為框架，選取17箇指標構建瞭初步的指標體繫，然後利用結構方程模型和湖北赤壁兩箇煤礦的調研數據，計算齣指標的權重併評估齣模型整體擬閤性，確定最終的評價指標體繫。結果錶明，各指標的權重中，對生態安全壓力、生態安全狀態和生態安全響應影響最大的因素分彆是工業三廢負荷壓力、水體（源）汙染和人均工業總產值，且模型整體擬閤性良好。

To find out major factors impacting coalmine area ecological security, the paper taking the pressure-state-response (P-S-R) model as the framework, selected 17 indicators established primary indicator system. Then using SEM and surveyed data from two coalmines in Chibi, Hubei, computed weight of indicators and estimated integrated fitness of the model, have determined final assess?ment indicator system. The result has shown that in the weights of each indicator, the most important factors impacting ecological secu?rity pressure, state and response are industrial 3 wastes load pressure, water body (waterhead) pollution and per capita gross industrial output value respectively, and the integrated fitness of the model is all right.
