- 摘要:
- 通过对森林各生态指标的评价，计算得出张家沟流域在1983～1993年10年间所种植的256.63hm2水保林，到1993年为止共取得的潜在经济价值1556.6万元，约为直接价值的8.58倍，从而阐明了森林潜在经济价值的重大意义。
- Abstract:
- The indirect economic value is the important component of the forest value with a great significance.The forest planted from 1983 to 1993 have acquired indirect economic value totalling 15 565 million yuan until 1993, it is 8.58 times the direct economic value.It is proved that the indirect economic value is of great importance.
