联合国环境规划署世界环境中心5月11日发表报告称,全球一半的竹类濒临灭绝.大熊猫等以此类植物为食的珍稀动物也将面临威胁.该中心的研究人员为了考察全世界竹类的分布情况,对数百份报告进行了汇总.他们发现,在全世界1200多种竹类中,大约有600种的原始生长地已减少到2万平方公里.面临威胁最严重的250多种竹类的生长地已经萎缩到2000平方公里.研究人员在报告中指出,竹类受到严重威胁的原因之一是,竹类遵循集体开花和死亡的生长规律.每一种竹的单株往往会在一个时期相继死去.而砍伐森林等人为原因都极易对竹林造成致命打击.
The World Environment Center of the United Nations Environment Program released a report on May 11th that half of the world’s bamboo species are on the verge of extinction.Rare animals such as giant pandas who feed on these plants will also face threats.The researchers in this center have investigated the world bamboo The distribution of the species, summarized hundreds of reports, found that about 600 of the more than 1,200 species of bamboo in the world had been reduced to about 20,000 square kilometers of their original area of growth. Growth of bamboo species has shrunk to 2000 square kilometers.Researchers in the report pointed out that one of the reasons bamboo is a serious threat to the population to follow the collective growth and death of the growth of the law of each individual plant often Will die one after another in a period of time, while deforestation and other man-made causes are extremely likely to cause a fatal blow to the bamboo forest.
