摘 要:清代,河南植被日益缩减。究其原因,除受明清时期我国气候日趋寒冷影响外,毁林垦荒、营建贩木、伐薪烧炭、采集木耳、灾荒摧残和烧取竹沥等活动,也影响着河南植被生存。植被减少之下,河南许多地方水土流失加剧、旱涝灾害增多、风沙扬尘肆虐、飞禽走兽减少和美景胜地消失,等等。实际上,保护植被也是在保护人类的生存环境。在发展社会经济时以及日常生活中,我们切不可随意毁坏植被,一定要增强生态环保意识,植树造林,爱护草木,保护、改善生态环境。当发展经济尤其是发展农业生产与生态保护矛盾时,前者要服从后者。否则,我们必将自食其果。Henan's vegetation was shrinking in Qing Dynasty. Deducing it's reason, in addition to Chinese climate was increasingly cold in Ming and Qing Dynasties, it was influenced by destroying forest to reclaim wasteland, construction and selling wood and bamboo, cutting wood to fire wood charcoal, collecting mushrooms, famine's devastation, burning and taking bamboo juice(竹沥), etc. Henan's vegetation reducing led to soil erosion, droughts and floods increasing, sandstorm raging, birds and beasts decreasing, beautiful scenery disappearing, and so on. in fact, we also protect our living environment when we protect vegetation. in agricultural production and daily life, we must avoid cutting and destroying vegetation arbitrarily, raise our ecological and environmental protection awareness, plant trees, protect grass and trees. the former should obey the latter when economic development, especially agricultural production development contradict with ecological protection. otherwise, we will suffer it's harm.
