Some scientists use models to simulate ecosystems
Since the late 1960S, ecologists have developed mathematical and other models that simulate ecosystems. Computer simulations can help scientists understand large and very complex systems (such as rivers, oceans, forests, grasslands, cities, and climates) that cannot be adequately studied and modeled in field and laboratory research. Scientists are learning a lot about how the earth works by feeding data into increasingly sophisticated models of earth is systems and running them on supercomputers.
Researchers can change values of the variables in their computer models to project possible changes in environmental conditions, help anticipate environmental surprises, and analyze the effectiveness of various alternative solutions to environmental problems.
Green career: ecosystem modeler
Of course, simulations and projections made with ecosystem models are no better than the data and assumptions used to develop the models. Ecologists must do careful field and laboratory research to get baseline data, or beginning measurements of variables being studied. They also must determine the relationships among key variables that they will use to develop and test ecosystem models.

一些科學家使用模型來模擬生態系統
從1960年代後期(末)以來，生態學家已經開發出數學和其他模型來模擬生態系統。電腦模擬可以(能)幫助科學家理解、了解這個巨大又非常(錯綜複雜)複雜的生態系統(例如河流，海洋，森林，草原，城市和氣候)在田野調查(實地研究)和實驗室研究、調查不能夠被充分地研究、調查與被塑造。科學家理解、了解很多關於地球是如何工作、運作，在超級電腦上藉由提供資料、數據輸入漸增複雜的、精密地球系統並運轉他們的模型。
研究人員可以(能)在他們的電腦模型改變變量推斷出在環境情況上可能出現的改變變化 幫助預期期望環境驚奇 並分析各式各樣的替代(可選擇)方案有效的解決環境問題。

當然，模擬和預測製造生態系統模型沒有比過去用來開發模型資料 數據和假設來的好。生態學家必須仔細的田野調查(實地研究)和實驗室研究，以獲得基本的資料數據，或開始變量的測量並研究。他們也必須確定關鍵變量之間的關係，它們將用來開發和測試生態系統模型。
