1985年以来,全国政协调查组及杨纪珂教授撰文提到:长江上游林区长期以来,由于经营方针失误,重采轻造,森林更新成效甚微,森林复盖率大幅度下降,以致形成气候异常,水量减少,增洪削枯,水土流失严重,因而提出了长江上游林区应停止采伐,改变以取材为为主的错误作法,实行以水源涵养为主的经营方针。这一建议提出后,引起各界人士的关注,不少同志认为:从林区所处的长江上游这—重要战略地位,从经营的方针上,把这部份林区作为水源涵养林,无疑是必要的。但从经营这片林区30多年的经验和林区的自然条件及我省的社会经济情况看,这片林区是否就认定不予采伐也是值得商榷的。川西林区到底可不可以采伐?如果说可以采,采多少?怎样采才合适,这些都是需要认真研究的。
Since 1985, the CPPCC investigation team and Professor Yang Jike have mentioned in the article that the forest area in the upper reaches of the Yangtze River has long been suffering from a failure in its management policies and the re-mining of light and light trees. As a result, the effectiveness of forest renewal has been negligible and the coverage rate of forests has dropped drastically, resulting in the formation of anomalous climate , Reducing water quantity, increasing flood and wasting water and soil erosion seriously, therefore put forward the wrongdoing that the forest area in the upper reaches of the Yangtze River should stop cutting and change the raw materials. After this proposal was put forward, people of all walks of life have drawn the concern of many people. Many comrades consider that this important forestry strategic position from the upper reaches of the Yangtze River in the region should be regarded as a water conservation forest from the operational guidelines. necessary. However, from the experience of operating this piece of forest more than 30 years and the natural conditions of the forest area and the social and economic conditions in our province, it is debatable whether this forest area is determined not to be harvested. In the end can be harvested in the western Sichuan forest? If we can adopt, how much mining? How to adopt the appropriate, these are the need to seriously study.
