| 摘 要： | 分析了中国南方石漠化现状及变化,以中国南方石漠化最为严重的贵州省为主要研究对象,研究了生态综合治理下石漠化的变化特征及发展趋势。数据表明:贵州省石漠化面积从2000年35 920km2(占全省总面的20.39%)发展到2005年的37 597km2(占全省总面的21.34%),5年间平均每年增加334.7km2。但与1975—1999年期间相比,石漠化增加的速度明显降低,生态治理工程一定程度上抑制了石漠化发展。贵州花江、清镇、毕节3个典型示范区石漠化监测数据表明,在生态治理工程实施下石漠化面积都逐年减小,说明石漠化是可以治理的,石漠化并不是"环境癌症"。但是,预测数据表明,即使《贵州省喀斯特石漠化综合治理规划》的工程措施全部实施,到2030年贵州石漠化面积将仍占全省国土面积的14.9%。中国南方石漠化问题将长期存在,石漠化治理是一个长期、艰巨的任务,绝非一两个五年计划就能达到"山川秀美"。要从根本上遏制石漠化增长的趋势和生态环境恶化的局面,仍需国家和地方在"十二五"期间及以后大规模的投入。

| Abstract: | The status quo and variation of karst rocky desertification in south China is analyzed.Taking Guizhou,the most serious karst roky desertification in South China,as a case,this paper dissuss the evolution trend and changing features of karst rocky desert under comprehensive treatment.Data show that the area of karst desert has risen to 37 597km2（accounting for 21.34% of the total area of Guizhou） in 2005 from 35 920km2（accounting for 20.39% of the total area of Guizhou） in 2000,increasing 334.7km2 annually in average within the 5 years.But comparing with that from 1975 to 1999,the average increasing speed of karst rocky desertification obviously slowed down,which proves that the ecologically comprehensive treatment restrained the desertification tendency to some extend.Monitor data in the Huanjiang and the Qingzhen as well the Bijie demonstration plots show that the area of karst rock desert decreases under ecologically comprehensive treatment,which proves desertification is not the so call environmental cancer but able to be controlled or cured.However,the monitor data also indicates that the area of karst desert will be still account for about 14.9% of the total area in Guizhou by the year 2030 even if the desert treatment brought into operation perfectly according with ＂the Integrated Rehabilitation Planning of Karst Rocky Desertification in Guizhou Province＂.Therefore,the desertification will last long and desert treatment will be a long term hard work that can not be completed within one or two Five-Year Plan.To keep down the tendency of desertification and environmental worsening radically,it is still necessary for the state and the government to increase large amount financial input for karst rocky desert improvement in the Twelfth Five Year Plan and the future. |
