This important statement for us to do a good job providing a dialectical thinking and the scientific method, fully embodies the dialectical unity of subjective and objective law. We must speak to the spirit for guidance, and further deepen understanding, targeted to long Yang well, Hawk shelters make good short, released in full development potential. 一 . Potential "and the" big five "short Board", that is, ecological environment, resources, water, economic development advantage advantage, advantage as policy overlap, cultural enrichment, and industrial boards, institutional weakness, short people short, short of funds and talent. From the perspective of ecological environment, our region as an important guarantee of national ecological safety, high forest cover, water, air and soil environmental indicators, such as the nature, is the development of green food and preserving pension ideal places, forest carbon sinks and other industries. From the perspective of the priority of characteristic resources, wild blueberry, Northern forest resources such as drugs, big snow, big wetlands, River and forest tourism resources, variety, large reserves of mineral resources such as molybdenum, lead and zinc, has translated into strong material conditions for economic advantage. Economic development out of the water, total more than 16 billion cubic meters of surface water resources and hydro-junction project of development prospects; recoverable reserves of high quality mineral water resources million tons, is the base of rare natural and pollution-free mineral water. Seen from the advantages of cultural enrichment, with Northern culture, and Xianbei cultures, Oroqen culture and a number of cultural resources, rock only found more than 1000 paintings, cultural industry development has great potential. From the perspective of policy overlap advantage, with the State Forestry Administration and the provincial government two channels of policy towards direct enjoyment of natural forest protection program, Western development, resource-based cities sustainable development and main function region construction national policy planning. As long as we put these resources to use and exploit the advantages of good, could give guanghui, snow, cold region and black Glebe into gold and silver, will provide strong support for forest development. (In addition to Jia Shuji mentioned advantages, XX we have in agriculture, water conservancy and other unique resources. Agricultural resources, 1.129 million mu of arable land throughout the County, da hinggan Ling was the only predominantly rural administrative districts, green planting area of 850,000 acres. Water resources, in a river over more than 180, many river hydropower development project conditions, rich in "three five Luo" and
