Abstract In order to provide scientific basis for controlling Erosion by Mining and Construction(EMC)., the erosion by mining and construction in Fujian province which resulted from industrial construction and mining, town expanding, traffic and others was surveyed based on GPS and GIS in 2002. The results showed that EMC was distributed densely and broadly over the province, that there are 4481 places existing EMC, the total area was 16671.36 hm2. The most of EMC were caused by industrial construction and mining, which occupied 73.56 percent of the total EMC, which had 3296 places. Moreover, 59.58 percent of the total EMC were under constructing process. The main causes resulting in EMC were that the scale of the exploitation and construction was becoming larger and larger, most of the owners had so apathetic conscience of soil and water conservation that hadn't taken the controlling measures, i.e. the workout ratio of soil and water conservation project was only 45.44 percent, and the practices for preventing land from erosion and executing the laws had not strong enough. Therefore, the practices for controlling EMC were suggested as follow: taking practicable and effective monitoring technology, strengthening supervising and executing the laws, increasing investment for scientific research, probing into scientific harness measures, carrying through prevention of EMC.
