The enforcement of Chinese forestry ecological restoration programs has made huge contribution to the socioeconomic development and ecological environment improvement of the country. At presesnt, Chinese ecological constuction is under the condition of "the equilibrium between ecological destruction and reparation". China has launched an ecology-centered strategy to constructing the system of forestry ecological and industry for the social demand of diversified foestry function. Forestry ecological restoration programs is not only concerned the realization of the forestry leap-forward strategic sectoral target of government, but also the ecological safety, sustainable harmonious development between nature and man of our country. Heilongjiang province is one main province of China forestry ecological restoration, and take forestry ecological restoration programs seriously from the three-north shelterbelt protection forest project that was initiated in 1978 marked the entry of large-scale construction period of Chinese forestry ecological restoration programs. In new era, it is important challenage for Heilongjiang province of how to improve the ecological condition and how to implement the construciton of forestry ecological restoration programs. Thus, It has very important theoretieal and practical meaning to study strategy and countmeasures for enhancement of the qualitity and effect of construction of forestry ecological restoration programs. Taking Forestry Ecological Engineering as the research object, the study employs the menas of integratnig comprehensive investigation with comparative study, qunatitative analysis with qualiattive analysis, and systematic analysis with demonsrtative analysis, Panel Discussion and present condition analysis. Through a systematic and comprehensive study, the fllowing basic conclusions are drawn:
     Heilongjian provincial forestry ecological restoration programs development will focus on:(1) following sustainable forest management principle; (2) clearly identifying Projects' goals, objectives and strategies;(3) diversifying basic principle contents;(4) enhancing the role of science and education; (5) indefatigably managing major key Projects;(6) enhancing Projects related legislations;(7)promoting urban forestry program along with fastened urbanization.(8)increasing wildlife protection areas and natural reserves;(9)enhancing wetlands protection and related restoration projects;(10)emphasising key water resources area's watershed management; andO(11)expanding provincial parks.
     Heilongjiang provincial forestry ecological restoration programs development principles are:(1) maintaining sustainable development and ecosystem services in a higher priority;(2). balancing forest ecosystem development with forest industry development, to seek simultaneous growth; (3) carrying on overall Projects advancement, but step by step implementation with focus on resolving major issues;(4) encouraging regional cooperation but with its own focus;(5) uniting government guidance with market regulations;(6) continuing new professionals training and putting them in important positions;(7) merging conventional skills with high leading edge technologies;(8) promoting self-innovation, also introducing, understanding, and utilizing existing technologies.
     Heilongjian provincial forestry ecological restoration programs strategies focus are:(1)Natural resources conservation program;(2) Affrestation and reforestation program (conversion from agriculture lands back to forests, or from grassland to forests);(3) Sanbei (northeast, northwest, and central north regions) protection forest projects (phase IV and V);(4) Wildlife protection and natural reserves;(5) Forest management;(6) Ecosystem service forests; and (7) Town and country greening project
