At last, the authors analyze the future research directions and research highlights, such as the theory and research methods, coupling model, and optimized water-heat structure of desert ecosystem. 最后,该文对水热平衡理论和研究方法、水热平衡耦合模型以及荒漠生态系统的水热结构优化模式等未来的研究方向和重点问题作了分析。 - 3
Regional ecosystem types, such as grass land, desert, and deciduous forest, are called biomes. 地区的生态系统,例如草原、荒漠和落叶林又被称为生物带。
