基于能值分析和生态用地分类的河北省生态补偿研究

Study on the Ecological Compensation of Hebei Province Based on Emergy Analysis and Ecological Land Classification

为促进河北省发展及生态环境建设,基于国内外相关研究方法,引入地貌类型空间尺度,将河北省划分为8个主要地貌类型区,应用生态补偿优先级模型,对河北省108个县的生态系统生产总值及生态补偿优先级进行测算,并从整体、地貌类型区、县3个空间尺度分析了河北省生态补偿的优先领域。结果表明:河北省生态补偿优先级总体较高,平均生态补偿优先级为0.221。空间上呈由北至南逐渐递减的趋势,山地丘陵区的生态补偿优先级大于平原地区。平原地区中,沿海平原的生态补偿优先级高于内陆平原地区。不同县、市的生态系统生产总值差异明显,因此生态补偿优先级也存在差异,有需要迫切补偿的围场、丰宁、黄骅、唐海、乐亭等地区,同时也存在应率先支付生态补偿的内陆平原县。将结果与经济补偿强度模型进行比较,既实现了河北省各地区生态补偿的迫切度的量化,又反映出河北省生态经济之间的关系,为促进京津冀的协调发展与生态环境保护发挥着重要的作用。

In order to promote the development and construction of ecological environment in Hebei area, based on the summary of the domestic and foreign related research methods, the introduction of landform spatial scale, Hebei Province can be divided into 8 landforms, GDP and the ecological compensation priority of 108 counties in Hebei Province were calculated by using ecological compensation system of ecological priority model, and priority areas of ecological compensation in Hebei Province were analyzed on the spatial scales of province, landform types, and counties. The results showed that ecological compensation priority of Hebei Province was generally high, the average ecological compensation priority was 0. 221, showing the gradually decreasing trend from north to south in space;the ecological compensation priority in hilly area was larger than the plain area, however, in the plain area, the ecological compensation priority of the coastal plain was higher than inland plains. Gross ecosystem production differences among counties were obvious, resulting in the different ecological compensation priority, urgent compensation in the northeast and the southeast coastal areas of Fengning, Huanghua, Weichang, Tanghai, Leting and other counties should be carried out, but also should take the lead in the payment of ecological compensation in the middle east, central and southern regions of the inland plain counties. The comparison of results and the economic compensation intensity model can not only achieve the urgent degree of quantization of the ecological compen- sation the area of Hebei Province, but also better reflect the relationship between the ecological economy in Hebei Province, and play an important rote in promoting the coordinated development of Beijing, Tianjin, environmental protection and efficient use of land resources.
