Abstract: Marxist resources conservation refers to the conservation as a result of the progress of science and technology， the recycled excreta from production， the aggregation of production and the collaboration of workers. Karl Marx criticizes the capitalist way of resources conservation， which strives to reduce the cost and improve the profit by exploiting workers. Mao Zedong and Deng Xiaopings thoughts of diligence and frugality as well as Jiang Zemins thought of comprehensive resources utilization have made Marxist resources conservation applicable in China. Since the 16th CPC National Congress， resources conservation has been regarded as an important measure to realize sustainable development， develop circular economy， promote frugal consumption and construct ecological civilization. Such thinking has enriched and developed Marxist thought of resources conservation.

Key words: Karl Marx, resources conservation, environment protection, Chinese Communist Party (CPC)
