<正>农作物秸秆因具有保温隔热性能，自古以来就是一种良好的建筑材料。随着科学技术的进步，以农作物秸秆为原料的复台墙体材料制造技术巳在中国得到发展。包括：平压法秸秆复合墙体、挤压法秸秆复合墙体、模压法秸秆复合墙体。笔者综述了3种墙体材料生产工艺、产品性能及其用途的研究现状和发展趋势。农作物秸秆墙体材料具有轻质、保温隔热以及吸音等特性，是一种理想的可用于室内或室外的建筑材料，在中国具有广阔的发展前景。

Based on the optimal structure analysis and optimal growing model curve estimation of the Jianhu shelterbelts, three scale scheme aiming at the study area was brought out. Applying the spatial analysis and statistics function of GIS, the spatial arrangement of shelterbelts of study area was accomplished. The result shows that the forest cover percent of study area was improved distinctly under the condition of optimization arrangement. The application of optimization arrangement of shelterbelts using GIS technology provides the straight and scientific foundation in shelterbelts management,
