| 摘 要： | 研制改进的基于空间最小景观单元的反距离权重景观开发强度法(CIWLDI方法 ),通过累积效应整合不同的土地利用分类,从能值的角度反映湿地生物完整性,客观有效地评价大面积湿地的景观健康。研究表明:大部分健康良好的湿地分布在苏州市郊,受到人类干扰相对较小,相反临近重点开发区域的湿地则退化严重。与其它方法相比,本方法可以有效地评价不同湿地之间的整体健康状况以及单个湿地内部的健康差异情况。在缺少现场观测数据的条件下,仅使用土地利用分类图就可以在短时间内完成对大范围湿地的健康评价。

Health Assessment of Wetlands in Suzhou Using Cell-based Inverse-distance Weighting Landscape Development Intensity |
| |
| Abstract: | Using improved method of cell-based inverse-distance weighting landscape development intensity, wetland health at landscape level was assessed objectively and efficiently. Different types of land uses were integrated to relfect the completeness of the biological system. Results showed that most wetlands with good health conditions, which were less affected by human disturbance, were located in suburban areas. In contrast, those with poor health conditions were degraded and commonly close to heavily developed areas. Compared with other assessment methods, our method can be used to assess the overall health situation of all the wetlands and the differences of health of individual wetlands. When lacking data of field observation, our method can implement health assessment in large area in short time using only the land-use classiifcation map. |
