摘要: 前言博斯腾湖位于新疆天山东段的焉耆盆地,面积988平方公里,是我国内陆地区最大的淡水湖[1]。在湖西南开都河三角洲前缘,即小湖区和湖西北的黄水沟洪积平原地区,发育有大片芦苇沼泽。本区芦苇沼泽受天山融雪水和地下水的补给,水分条件较好。土壤以腐殖质沼泽土、泥炭土和盐化泥炭土为主。该区处于欧亚大陆腹地,属大陆性干旱气候区,芦苇生长期内日照长、积温高、昼夜温差大,适宜芦苇的生长发育。因此,博湖芦苇株高、径粗、叶茂、纤维长,是我国重要的优质芦苇生产基地之一。

Abstract: It was efficient and reliable to investigate the reed resource of Bositeng Lakein Xinjiang province,characterized by complicated types of reed land and verydifferent reed growth using colour infrared airphotos,Landsat images andmultiband imagery.At first,based on Landsat images and relevant data,we conducted(regional preinterpretation)to analyze ecological environment of study area,thecharacteristics of reed land types and imaging mechanism to determine the programfor abstracting remote sensing information and aerial photographic conditions. On the processed Landsat images and airphotos,we considered typicallygeographic features and reed land types,preselected ground sampling sectionsand spots,then determined indexes classifying reed land types according tosampling data and image characteristics,established various interpretation keys,drew distribution maps of reed land types and measured the area of varioustypes of reed land following geometric correction.On the other hand,based onsampling values and habitat Conditions of reed,we divided study area into anumber of pieces,estimated weight per unit area with weighted average methodone piece by one piece,finally calculated the total reserve of reed resource.
