| 中文摘要 | 从生物多样性保护的角度,采用多尺度遥感影像分割方法中的人为干扰度模型,计算分割阈值确定湿地生态廊道的宽度,并结合聚类分析法分类的8种人为干扰类型,对建三江地区廊道结构设计进行了研究。结果表明,廊道分割阈值设为20%,非湿地背景噪声为9.43%,湿地生态廊道最佳宽度为1298m。8种人为干扰度中聚类c1、c2、c3和c4类型是受人为干扰较弱的区域,主要分布在浓江、乌苏里江、三江和洪河保护区原始生态环境区域,将其分别设定为核心区、实验区、边缘区、缓冲区4种类型。廊道核心区中的沼泽类型占75%,总体精度高达93.7%,实验区沼泽占72.2%,精度达到75.8%,边缘与缓冲区起到边缘护栏的作用,缓冲区宽度为945m,本研究为湿地生态廊道的建设与修复提供了可靠、科学的参考依据。 |
| 英文摘要 | For the protection of eco-environment and biodiversity in Jiansanjiang area of Northeast China, themethod ofmulti-scale remote sensing image segm entation was adopted to design an ecological corridor between two national nature reserves San jiang and Honghe. The width of this corridorw as defined by calculating the division threshold value of NDVI standardized change intensity index, and the structure of the corridorw as designed by using a moving window algorithm and aK-means cluster ana lysis algorithm. The div ision thresho ld value w as set at 20% , background no ise o f non-we tland w as at 9143%, and optima lw idth o fw etland eco log ical corridor was 1298m. Among the regions suffered from eight different intensities of human disturbance, clusters c1, c2, c3, and c4 were the regions less affected by human disturbance, mainly distributed in the primitive eco-environment of Nong jiang River, Wusuli River, San jiang Nature Reserve, and Honghe Nature Reserve. To construct thew etland ecological corridor between the two nature reserves, the c1, c2, c3, and c4 were defined as -core. , - test. , -marg inal. , and -buffer. zones, respectively. In -core. zone and - test. zone, swamp occup ied 75% and 7212% , with an accuracy as high as 9317% and 7518%, respectively; and -marg ina l. and -buffer. zones played the role of edge guardrai.l The width of the -buffer. zonew as 945m. Our study provided areliable and scientific reference for the construction and restoration of wetland ecological corr-idor. |
