摘要
本研究在核算甘孜州草地生态系统生态破坏损失价值的基础上,通过对比生态保护与建设实际投入、生态破坏损失占比情况,分析了甘孜州各县草地生态保护与建设资金投入结构,构建了绩效评价指数。研究结果表明,2014年甘孜州因人为造成的草地生态破坏损失达到62.5亿元,占同期GDP的30.2%,石渠、色达、理塘、德格、康定、白玉、甘孜等县生态破坏损失总量大、单位草原面积的破坏损失压力也较大。2011—2014年甘孜州草地生态保护与建设资金投入方向正确,但各县仍趋向平均,除石渠外,大部分重点县的保护投入占比均低于生态破坏损失占比,雅江和乡城的投入比例偏高。基于生态破坏损失的甘孜州草地生态保护与建设绩效明显,2011—2014年草地保护投入29.08亿元,生态破坏损失价值降低了76.25亿元,其中,炉霍、康定、道孚、巴塘和德格5个县的绩效高于甘孜州平均水平,而雅江、乡城、白玉县的绩效水平相对较低。
The research on the basis of accounting the loss value of grassland ecosystem damage in Ganzi,studied the performance evaluation of grassland ecological protecting and constructing funds during 2011 to 2014,and analyzed the structure about funds invested in each county.The results showed that the economic losses from grassland damage reached 6.25 billion yuan in 2014,accounted for 30.2%of GDP.These counties of Shiqu,Seda,Litang,Dege,Kangding,Baiyu and Ganzi were relatively bigger in both the total damage losses and unit area losses.The performance of grassland ecological protection and construction based on the economic losses was obvious in Ganzi,that is,during 2011 to 2014,the government invested 2.908 billion yuan for grassland protection,the economic losses reduced by 7.625 billion yuan.In addition,the performance at Luhuo,Kangding,Daofu,Batang,Dege were higher than the average level.Overall,the investment in grassland protection and construction was in the right direction,but compared with the damage losses,the ratio of actual investment was still less and tended to be uniform at the serious damaged counties except Shiqu County.
