黄河三角洲高效生态经济区是一个不久前列入“国家战略”的新型经济区,土地资源丰富是其最显著的地域优势。由于该区范围涉及的政区类别多样,过去一直没有作为一个整体进行土地变化与开发利用的专题研究。本文通过收集该区域不同年代的遥感数据进行解译分析,第一次合成、绘制了新区范围的多幅遥感影像图和资源评价图,并分别对其历史环境演变、土地利用格局及水盐运移特征等进行评价与研究,有针对性地提出了规模化治理盐碱地的工程措施。
The Yellow River Delta High-Efficiency Ecological Economic Zone is a new type of economic zone not long ago listed in the “national strategy”. Its abundant land resources are its most prominent geographical advantages. Due to the diversity of political categories involved in the area, there has been no thematic study on land change, development and utilization as a whole. Based on the interpretation and analysis of the remote sensing data collected in different years in this area, this paper synthesizes and draws a number of remote sensing image maps and resource evaluation maps in the new area for the first time and respectively analyzes the evolution of its historical environment, land use pattern, Shift characteristics and other evaluation and research, put forward a targeted scale of engineering measures to control saline-alkali land.
