摘要
绿色发展是生态文明建设的必由之路,绿色发展指标是生态文明建设评价的重要内容,全面、快速、动态地获取绿色发展指标并进行准确评价意义重大。传统的绿色发展指标获取受数据采集方式的限制,难以在数据时效性和覆盖范围上满足评价要求,卫星遥感技术因其综合、动态、快速、大范围获取数据的优势,有望在绿色发展评价中发挥重要作用。聚焦绿色发展的科学内涵和目标,在系统梳理国内外绿色发展指标获取、评价方法和评价体系的基础上,提出了应用卫星遥感技术开展绿色发展评价的指标选择、技术流程和评价方法,并在中国西部延安—榆林地区进行了实证研究。结果表明:延安—榆林地区绿色发展程度空间上由南向西北呈现逐渐降低趋势;榆林西北部和东南部生态环境脆弱,绿色发展程度相对较低;延安地区绿色发展程度总体高于榆林地区。在小范围应用的基础上,结合西部地区绿色高质量发展评估的需求,建议构建中国西部绿色发展监测网络和大数据平台,充分发挥自然资源数据在国家西部大开发重大工程、重大项目科学决策中的支撑作用。
Green development is the way leading to ecological civilization. Green development index is essencial for evaluating the level of ecological civilization, as well as for assessing the construction degree of beautiful China and a well-off society in an all-round way. It is of great significance to comprehensively, rapidly and dynamically obtain the data of green development index and carry out accurate evaluation. However, the traditional investigation methods are difficult to meet the evaluation requirements in terms of data timeliness and coverage. Satellite remote sensing technology is expected to play an important role in green development evaluation due to its advantages of comprehensive, dynamic, rapid and large-scale data acquisition. Focusing on the scientific connotation and objectives of green development, the green development index acquisition, evaluation methods and evaluation systems were systematically summarized in China and abroad. The index selection, technical process and evaluation method of green development evaluation were put forward by using satellite remote sensing technology. Finally, the application test was carried out in Yan’an-Yulin area. The results show that the degree of green development in the area gradually decreases from south to northwest, and the value in Yan’an area is usually higher than that in Yulin area;the ecological environment in the northwestern and southeastern Yulin area is fragile, and the corresponding degree of green development is relatively low. Based on the small-scale application, the following outlook is made in conjunction with the needs of green and high-quality development assessment in western China. It is suggested to build a monitoring network and big data platform for green development in western China, and give full play to the supporting role of natural resources data in the scientific decision-making of critical engineering and major projects of China western development.
