摘要: 根据梭梭的分布规律、生境条件、林分结构、群落特征,利用十几年调查资料,把准噶尔盆地荒漠梭梭林划分成五个林型组、十四个林型。一、石质山麓梭梭林型组:生长在浅山沟谷,剥蚀山坡、台地、低山,共一个林型;二、砾质戈壁梭梭林型组:生长在山前洪积扇或砾质戈壁地带,共一个林型;三、土质梭梭林型组:生长在冲积-淤积平原上,是梭梭生长的最佳立地类型,共六个林型;四、沙质梭梭林型组:生长在沙漠内的低矮沙丘和平坦沙地,共三个林型;五、沙丘沙地白梭梭林型组:白梭梭分布区域狭窄,只限于沙漠内的沙丘或沙地,共三个林型。但短命类植物-沙拐枣-白梭梭林型,因沙拐枣种的不同而分成三个亚型。

Abstract: Acording to the law of distribution, the habitat condition, the stand structuve and the characteristics of community, the haloxylon fovest in the Junggar-basin desert can be divided into five forest-type groups and fourteen forest types. 1. The rocky piedmont group of forest type only has one forest type. They are distributed in valleys, on denuded slopes, tableland and low mountain. 2. Gravel gobi group of forest type. They are growing on piedmont diluvial fan or gravel gobi zone and only has one forest type. 3. Loamy soil group foest type. They are growing over alluvial-diluvial plain with flat terrain, fine texture and dense plants. It is the best type of habitat condition. There are six forest types. 4. Sandy soil group of forest type. They are growing on low sand dunes and sandy flat in the desert, threr are three forest types. 5. Sand dune and snad land group of Holoxylon persum forest type. The Holoxylon persum distribution area is rather narrow and they only grow on sand dunes and sandy land in the desert. There are three forest types. The ephemeral calligonum mongolicum-Holoxylon persum forest types can be subdivided into three forest types based on the Calligonum species.
