GDP only reflects the quantity of country′s economic growth, but can not reflect the quality of that growth. Seeking a sort of accounting method which considers natural and environmental resources loss to measure true state of a country′s economic growth is an urgent problem to settle at present. Currently some countries and international organizations pay much attention to study Green GDP, and gradually build up resource checking account. Using resource index accounting reflects the relationship of economic growth、resources and environmental pressure.Both domestic and foreign, which Green GDP system has a unifies dimension measuring unit for natural and environmental resource and how to set price of natural resource losses is an unresolved issue for Green GDP accounting.Based on a few present defects in the accounting of Green GDP, the article applies energy theory method to discuss Green GDP checking. Taking solar energy as the measuring dimension of natural and environmental resources set price for natural resource with energy\|currency value. This not only solves the problem of inconsistency in natural and environmental resource measure unit while checking Green GDP, but solve the docking problem between the value of natural and environmental and economic society. Utilizing Odum′s emergy theory and method of economic system, unrenewable resources and environmental losses in process of national economic production, in Huaihua of Hunan Province in 2006, were quantitatively analyzed.It calculates emergy of consumed unrenewable resources and environmental losses as well as emdollar value, thus accountes Green GDP of Huaihua City in 2006. The results indicate that emdollar balue 9.70 108＄ of environmental losses are consumed in process of national economic production in huaihua in 2006.The results of this study os the same as Wangzheng Barro model、Asheim’s Green GDP checking model and GDP in Shanghai (1955-1995)is double to four times Green National product, it’s also similar to the relationship between USA(1950-1999)per capita GDP studied by Mark Anielsk, and Genuine progress indicator, Italy (1960-1990)per capita GDP studied by Giorgio cuenno and the result of Index Sustainable Economic Welfare. Huaihua City in 2006 in GDP there is about 25.44% at the cost of consumption of natural rosources and there is about 43.95%at the cost of enviornmental losses. Green GDP in huaihua enly holds 30.01% of GDP. The article discusses the scientificity and rationality as well as deficiency of emergy analytic approach in account of Green GDP, it also considers that when we check unrenewable environmental resources in the account of Green GDP, the energy analytic methed can be used which can reflect true value of natural resources; when we renovate environmental losses, investment cost method can be utilized which is more in line with actual situation to the current environmental management in process of national economic production.
