中文摘要：

对全球二氧化碳、全球温度变化、全球大气水汽和全球植被变化进行了分析,分析结果表明,全球水汽分布与温度变化同时影响植被时空分布,水汽变化和植被时空变化影响着全球温度变化,同时调节或者部分抵消了二氧化碳＂温室效应＂的影响,使得地球对温度变化具有自我调节功能。通过天体运行轨道分析,指出地球温度变化主要由地球在太阳系中的轨道能级位置决定,气象（天气）和生态系统时空变化是地球内部系统为适应天体运行（太阳系和银河系）轨道位置变化的主要内在调节形式。通过建立太阳系围绕银河系运行的简单模型图,提出地球磁场逆转或者大的变化是由于太阳运行轨道位置临界点转换而形成（类似地球的春分、夏至、秋分和冬至）,地球等星体运行轨道呈椭圆形主要是由于太阳同时也在运动造成,地球上不同时期各种生物的出现、迁移和消失是由天体运行轨道位置决定。在此基础上提出了建立以开普勒定律和万有引力定律以及广义相对论为基础的全球气候变化和生态系统模型思想,此理论思想的提出为大时空尺度空间气候变化和生态系统模型研究开辟了新的研究途径和新的学科研究方向,对空间气候变化和灾害预测以及生态物种时空演化等研究具有重大意义。

英文摘要：

Stars＇ orbits are analyzed,and the changes of global temperature,water vapor,carbon dioxide,and vegetation are analyzed. The results show that the earth＇s temperature is mainly determined by the earth＇s orbital location in the solar system,and carbon dioxide for temperature change is just a disturbance or a fine-tuning role. The space-time variation of the meteorological（weather） and ecological system is the main regulation form when celestial bodies are moving,and the spatiotemporal distribution of the ecosystem is greatly influenced by the temporal and spatial distribution of atmospheric water vapor（rainfall）,which is also determined by orbital positions of celestial bodies on a large scale. Temporal and spatial variation of water vapor content,rainfall and vegetation adjust the greenhouse effect of carbon dioxide,and vegetation adjusts the temperature through absorption and emission of carbon dioxide. The global change research should be divided into two levels： the one taking the earth system as the core of the system,and the other focusing on the extra-system research which considers other planetary orbital changes,the changes of Earth＇s gravitational field and magnetic field,and solar radiation changes. A model for global climate-ecosystem＇s changes is proposed based on Kepler＇s law-universal gravitation law and general relativity,which is of great significance to forecast of spatial climate change,natural disasters and ecological system＇s spatial evalution.
