摘要
依据景观生态学的理论和研究方法,运用遥感和地理信息系统技术,在草地资源分类的基础上,对昭苏县草地资源景观格局的斑块水平指数、斑块类型水平指数以及景观水平指数进行数量分析及评价,明确其草地资源类型空间分布特性。研究结果表明,研究区山前平缓地草地和低山丘陵草地受非草地类型及人为因素干扰强烈;随着时间的变迁,总体景观格局随着年度的推移出现景观破碎度、优势度和多样性增加,均匀性下降的趋势。
According to the theory and methods of studying landscape ecology and by using GIS and RS technologies, the Zhaosu county's rangeland resources were analyzed and appraised on the basis of their classification system, cartography, and distributing characteristic. The rangeland of experiment site on the level land in front of a mountain range and those on low mountainous and hilly areas have suffered serious disturbances generated by human activities. The entire landscape is fragmented, serving while the other functions are curtailed.
