根据1996年初省护林防火办公室编制的《河南省生物防火林带工程建设规划报告》,到2010年,我省将营建防火林带5.6万公里,折合有效面积13.1万公顷,其中改建防火林带3.0万公顷,占规划林带总长度的54.2%。现就如何改造现有林为防火林带的问题探讨如下。 一、改建防火林带的意义和作用 我省现有230万公顷的森林面积,且广大林区多交通不便,若伐掉现有林重造防火林带,成本高、恢复难,得不偿失。因此,有计划、有步骤地改建防火林带具有十分重要的意义。
According to the “Planning Report on Construction of Biological Fire Belt Project in Henan Province” prepared by the Provincial Forest Fire Prevention Office in early 1996, by the year of 2010, 56,000 km of fire-resistant forest belts will be constructed in our province, equivalent to 131,000 hectares of effective area, of which 30,000 hectares will be rebuilt, Accounting for 54.2% of the total planned forest belt length. Now on how to transform the existing forest for the issue of fire forest as follows. I. Significance and Role of Reconstruction of Firebreak Belt In our province, there are 2.3 million hectares of forest area. Besides, there are many traffic inconveniences in the vast forest area. If the existing forest is rebuilt to fire fire-retardant forest belt, the cost will be high and it will be difficult to recover. Therefore, it is of great significance to rebuild firebreaks in a planned and systematic manner.
