摘要
基于地理信息系统技术及景观生态学原理,在利用综合指数法初步构建的景观生态安全综合评价模型基础上,利用RS和GIS技术对遥感影像及其他带有空间属性的数据进行了处理、分析,并根据太阳岛湿地景观生态安全评价结果将太阳岛湿地生态安全状况划分为3个层次:生态安全程度相对较高的区域,主要为水域、天然草地、部分林地等自然景观;生态安全程度中等区域,主要为部分草地、片林和风景旅游区等半自然景观;生态安全程度相对较低区域,主要为部分未利用地、城镇居民点和耕地等半自然景观和人工景观。根据评价结果,对太阳岛相应区域提出了具体的保护和恢复措施。
A comprehensive evaluation model for ecological security of wetland landscapes in the Sun Island Scenic Spot of Harbin City,Heilongjiang Province was developed based on GIS technology and landscape ecology theory.TM remote sensing data were processed based on RS and GIS,and a database of the Sun Island was also established.Security of wetland landscape in the Sun Island was divided into three levels,namely relatively high security areas including natural landscapes such as water area,lawn,and part of forests;medium security areas including semi-natural landscape such as grassland,woodland,and tourist area;lower security areas including a few parts of semi-natural landscapes and artificial landscapes such as abandoned land,residential area,and infield.Some countermeasures on the protection and restoration of the Sun Island were put forward for different security areas.
