摘　　要：生物多样性价值的定量研究是生态系统服务价值研究的重点与难点。论文以河北省黄骅市滨海土地为研究对象,借助RS、GPS和GIS现代信息技术,利用遥感影像数据及303个样点调查数据,提出一种更全面准确的生物多样性价值估算方法。结果表明:生物多样性价值分为生物多样性价值Ⅰ和生物多样性价值Ⅱ,生物多样性价值Ⅰ用NDVI指数反映植被覆盖与分布价值,生物多样性价值Ⅱ用生物多样性指数反映物种种数价值,总价值由耕地、建设用地、园地、其他土地、盐碱地、湿地、水域、盐田到草地逐渐降低,经市场法和意愿法检验,结果可信。The quantitative study of biodiversity value is the key point and difficul of researching on ecosystem services value. Taking Huanghua. coastal land in Hebei province as a case, using modern information technology with RS, GPS and GIS, and using the data of remote sensing images and 303 sample survey data,the article put forward a more comprehensive and accurate method for estimating biodiversity value. The results showed that biodiversity value was divided into biodiversity value Ⅰ and Ⅱ. The total value of all classes of biological diversity could be calculated by marketing methods. Biodiversity value Ⅰ reflected the vegetation coverage and distribution with NDVI index. Biodiversity value Ⅱ reflected number of species with biodiversity index. It showed that biodiversity value was decreasing from farmland, construction land, corner, other land, saline land, wetland, water, salt pan to grass land. The results were trusted by applying the market method and intention method to analyze the credibility.
