Energy analysis for the sustainability of an agro‐ecosystem in Ningxia province,China

摘要：

An important challenge facing China today is the feeding of an increasing population with decreasing energy supplies and finite environmental resources.To meet this challenge the sustainability of agricultural methods must be evaluated to determine how yields can be maximized relative to their resource use and environmental degradation.The Agro‐Pastoral Transition Zone of Northern China is an important ecotone (eco‐zone ?).Therefore, the discovery of new tools for sustainable natural resource management in these areas is particularly vital.
