内蒙古科尔沁沙地腹地G304国道植被物种调查

处于内蒙古科尔沁沙地腹地的G304国道两侧沙化现象严重，随时都面临着沙尘的侵袭，严重时造成交通堵塞，宜建立植物防沙体系。先调查研究G304国道两侧的植被物种，根据当地的气候条件和植物的生物学特性，营造防沙体系。结果表明，小叶锦鸡儿、差不嘎蒿是该路段乃至科尔沁沙地的建群种和优势种。小叶锦鸡儿——差不嘎蒿群落是这里的顶级植被，属土壤演替性质，可视为土壤——气候演替顶级，并表现出特别耐寒风沙抗干旱的生态生物学特性。它们是植物防沙体系首选灌木、半灌木种群。小叶杨、旱柳则是这个体系首选的乔木树种。乔、灌、草2~3行相间排列组合是这个体系防沙功能最佳、结构最优化的配置。夏秋移栽乔、灌木和雨季种植灌木、半灌木及其沙生植物是G304线植物防沙体系主要技术措施。

The G304 National Freeway of Inner Mongolia Tong Liao Kerqin SandPlants the Quilt Species Investigating the Research

Summary The G304 road located the hinter land of Kerqin sandlot where should built vegetable system against sand. The community of Caragana micophylla and A.holodenborn is the super vegetation, which is the character of soil succession of soil-climate,also it displays special ecology and biology character against sand and drought.They are the chief choice in bush and half-bush and Populs simouii,Salix magudana are the chief breed in this system. Arbors/bushes/grasses arranging alternately in 2-3 lines is the best arrangement in function and structure against sand.Invertigation shows that Caragana microphylla Artemisia olodenbron are the dominant species and constructive species.Trans-planting arbors and bushes in summer or fall and planting bush/half-bush/sand-plant in rainy season are the main technical measure in the sand-proof system of G304 road.
