技术简介

采用GRACE重力卫星以及MODIS卫星影像数据，识别沿线国家水资源开发、土地利用等方面变化趋势与时空变化特征，并建立需水量及水资源可持续利用分布模型，综合评价研究区域水安全。在此基础上，耦合种植结构调整、节约用水等适应对策建立研究区域水安全决策支持系统。

Introduction

The GRACE gravity satellite and MODIS satellite imagery data are used to identify the trends and temporal- spatial change characteristics of water resources development and land use in the countries along the Belt and Road Initiative,and to establish a distribution model for water demand and sustainable utilization of water resources,thus comprehensively assessing water security in the area.On this basis,a decision support system for water security in the area is established,coupled with adaptation measures such as planting structure adjustment and water conservation.
