基于植被净初级生产力的煤矿区生态损失测度研究

以江苏徐州九里矿区为研究对象,采用基于遥感过程的CASA模型测算植被净初级生产力（Net Primary Productivity,NPP）,研究结果表明：采用植被净初级生产力对矿区生态环境进行测度是可行的;从1987年到2008年间矿区NPP从18.019减小到9.261 gC/（m2.月）,NPP平均变化量从0.293增加到3.389 gC/（m2.月）,表明随着开采活动增强,矿区生态损失量增大;生态破坏区内NPP的变化范围为2.752～4.752 gC/（m2.月）,生态影响区NPP的变化范围为0.152～0.352 gC/（m2.月）,生态破坏区内NPP的变化量大于生态影响区;NPP的...

Summary:以江苏徐州九里矿区为研究对象,采用基于遥感过程的CASA模型测算植被净初级生产力（Net Primary Productivity,NPP）,研究结果表明：采用植被净初级生产力对矿区生态环境进行测度是可行的;从1987年到2008年间矿区NPP从18.019减小到9.261 gC/（m2.月）,NPP平均变化量从0.293增加到3.389 gC/（m2.月）,表明随着开采活动增强,矿区生态损失量增大;生态破坏区内NPP的变化范围为2.752～4.752 gC/（m2.月）,生态影响区NPP的变化范围为0.152～0.352 gC/（m2.月）,生态破坏区内NPP的变化量大于生态影响区;NPP的降低量与煤矿生产能力成正相关。矿井投产期NPP开始降低,稳产高产期NPP降低量最大,衰退期NPP降低幅度开始减小并且NPP有增大的趋势,矿区生态环境向良好的方向发展。

Taking Jiuli mine area of Xuzhou as an example,a NPP evaluation was taken by CASA model.The results indicate that：it is available to scale mining eco-environment by NPP;during the period of 1987—2008,the NPP decreased from 18.019 to 9.261 gC/（m2·month）,and the average variation of NNP increased from 0.293 to 3.389 gC/（m2·month）.With the increase of mining activity,ecological loss increased gradually;the variation of NPP in the ecological damage area was from 2.752 to 4.752 gC/（m2·month）.The variation of NPP in the ecological influencing area was from 0.152 to 0.352 gC/（m2·month）.The average variation in the ecological damage area was greater than the ec
