以广西大化县为研究区,运用大化县石漠化遥感监测数据和基础地理信息数据,提取石漠化信息的相关属性,并进行数据统计和分析。结果表明:岩溶地貌区的石漠化发生率排序为:岩溶槽谷>孤峰丘陵及平原>峰林洼地>岩溶丘陵>峰丛洼地。各坡度石漠化的发生率存在一定的规律。基岩裸露度、植被综合盖度和土层厚度是判定石漠化程度的重要因素。
以廣西大化縣為研究區,運用大化縣石漠化遙感鑑測數據和基礎地理信息數據,提取石漠化信息的相關屬性,併進行數據統計和分析。結果錶明:巖溶地貌區的石漠化髮生率排序為:巖溶槽穀>孤峰丘陵及平原>峰林窪地>巖溶丘陵>峰叢窪地。各坡度石漠化的髮生率存在一定的規律。基巖裸露度、植被綜閤蓋度和土層厚度是判定石漠化程度的重要因素。

Taking the Dahua county in Guangxi as an example ,by using rocky desertification mo‐nitoring results of the data of the Dahua county and its basic geographic information data for statistics and analysis ,the study indicates that the occurrence of rock desertification of different Karst landform areas is in order as Karst trough valley> Koho hills and plains> Hoodoos depression> Karst hills>Cluster‐peak depression .There is a regular pattern of rocky desertification rate in different slopes .Ex‐posed bedrock degree ,the vegetation comprehensive coverage ,soil thickness are the three most im‐portant factors to determine the rocky desertification degree .
