| 摘 要： | 据估算,宝天高速公路建设过程中永久性征地和临时性用地所造成的生态系统服务价值的损失分别为249.34万元/a和190.45万元/a;修路过程中造成小陇山林区森林生态系统服务价值的损失分别为109.74万元/a和127.72万元/a,分别占小陇山林区森林生态系统服务价值的0.0105%和0.0122%,四大林场森林生态系统服务价值总和的0.0455%和0.0530%。由于修路过程中所造成的森林生态系统服务价值的损失很小,所以不会对小陇山林区及四大林场的森林生态系统的生态服务功能造成很大影响。

| Abstract: | According to the estimated results,the lost values of ecosystem service caused by permanent and terminal land use of Baotian motorway in Tianshui city were about 249.34?190.45 wanyuan/nian.And the lost values of forest ecosystem service caused by permanent and terminal land use of Xiaolongshan forestry centre were 109.74?127.72 wanyuan/nian,which accounted for 0.0105%?0.0122% of the total value of forest ecosystem service of Xiaolongshan forestry centre,and which accounted for 0.0455%?0.0530% of the total value of forest ecosystem service of four forestry station.Because the proportion of the lost values of forest ecosystem service caused by permanent and terminal land use was very small,the construction of Baotian motorway in Tianshui city will not affect the function of forest ecosystem service of Xiaolongshan forestry centre and four forestry station. |
