基于遥感与生态服务模型的青岛市生态保护重要性评价

Evaluation of Ecological Protection Importance in Qingdao based on Remote Sensing and Ecological Service Model

生态保护重要性评价是"双评价"的重要组成部分,是合理规划国土空间的重要依据。提出一种将遥感数据作为主要驱动数据,采用生态服务模型与生态敏感性指数相结合的生态保护重要性评价方法,定量评价了2018年青岛市陆域的生态保护等级。依据"双评价"标准,综合考虑区域内重要生态服务功能区、生态脆弱区和生态保护因子,划定青岛市生态保护重要性,并根据生态保护红线对评价结果进行验证和分析。结果表明:基于遥感与生态服务模型的生态保护重要性评价方法能够较好地评价区域生态保护重要性,青岛市生态保护重点区面积为1125.57 km^(2),约占全市陆域面积的10.34%,主要分布在青岛市东部的崂山片区、西南部的胶南山区以及北部的大泽山片区等生态系统服务功能较为丰富且生态敏感性较高的部分地区。研究提出的生态保护重要性评价方法为"双评价"工作的开展提供了良好的技术支撑,评价结果对于科学合理地编制城市发展规划和建设生态文明城市具有重要的参考价值。

The importance assessment of ecological protection is an important component of the"double evaluation".It can reflect the importance of ecological functions in different environments in the region,and protect the ecological security of the district which includes the ecologically fragile areas and the key areas of ecological service functions.This paper proposes an ecological protection importance assessment method,which uses remote sensing data as the main driving data and combines ecological service model and ecological sensitivity index to quantitatively evaluate the ecological protection level in the whole land area of Qingdao.The method comprehensively considers the important ecological service function area,fragile area and protection factors,delineate the importance of ecological protection in Qingdao.The assessment results are verified according to the ecological protection red line.The results show that the proposed method is reliable for ecological protection importance assessment,and the area of Qingdao’s key ecological protection is 1125.57 km^(2),accounting for 10.34%,mainly distributed in the area where the ecological service functions are richer and the ecological sensitivity are more vulnerable,including Laoshan mountain region in the east,the Jiaonan mountain region in the southwest,and the Dazeshan region in the north.In this paper,remoting sensing data as the main driving data provides a good technology support for the"double evaluation",and the results have important reference for the scientific and rational compilation of urban development planning and construction of ecological civilization city.
