看了这个调查报告,感到很高兴.陕北地区治理水土流失,改善生态环境的措施和经验是好的.我国是一个有几千年历史的文明古国.包括甘肃、陕西在内的黄河流域,是我们中华民族的主要发祥地.陕西曾经是周、秦、汉、唐等十三个王朝的建都之地,在古代历史上相当长的时间内,陕西、甘肃等西北地区,曾经是植被良好的繁荣富庶之地,所谓“山林川谷美,天材之利多”就是古来描绘陕西一带的自然风物的.司马光的《资治通鉴》中描述盛唐时期陕、甘的发展情景是“闾阎相望,桑麻翳野,天下称富庶者无如陇右”.后来由于历经战乱的破坏,加上自然灾害和滥砍滥伐造成的损失,导致了陕、甘等西北地区的严重沙化、荒漠化,经济文化的发展也因此受到极大制约.
