云南糯扎渡保护区电站建设水淹区植被资源调查

为了掌握水电站建设水淹区的植被资源决策数据和信息，利用3S技术对糯扎渡省级自然保护区水淹区的植被资源进行调查。结果表明，被淹没的植被类型和面积分别为：季风常绿阔叶林313hm^2，占保护区面积的2．8％；落叶季雨林443hm^2，占33．5％；思茅松林10hm^2，占0．2％；竹林385hm^2，占41．2％；干热河谷稀树草丛73hm^2，占65．2％；灌木林9hm^2，占2．2％。在水电站建设水淹区的植被资源调查中3S技术展现了速度快、精度高且经济的特点。

Inventory of Vegetation at the Flooded Area After the Construction of Hydroelectric Station in Nuozhadu Nature Reserve of Yunnan

In order to get the data and information on the vegetation resources within the Nuozhadu nature reserve,which is going to be flooded after the Nuozhadu hydroelectric station is established,forest inventory was conducted with the aid of 3S techniques.The results of inventory showed that,the flooded vegetated area would be 313 hm~2 of monsoon ever-green broadleaved forests,which accounted for 2.8% of the total amount of this vegetation in the nature reserve,443 hm~2 of deciduous seasonal rain forests,which accounted for 33.5%,(10 hm~2) of Pinus kesiya var.langbianensis,which accounted for (0.2%),385 hm~2 of bamboo forests,which accounted for 41.2%,73 hm~2 of dry and hot valley savanna,which accounted for 65.2%,9 hm~2 of brush forest,which accounted for 2.2%.This inventory provided the fundamental data for the environmental impact assessment and management of the nature reserve.
