The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

Due to food pressure, grain product in the western Jilin Province will be enhanced in the near future. Farmland areas in the area will be decreased slowly in the near future, but with the technique development of irrigation establishment, paddy areas and utilization amount of fertilizer and pesticides will be increased rapidly. So, the NPS pollution from farmland will be more serious. The main lakes in the areas such as Moon Lake and Qagan Lake have been polluted by N and P, and the content of salt in the Nenjiang River has been increasing since last 30 years. All of these show that the negative effects of NPS pollution in the area have been serious and should not be neglected by the scientific research and corresponding government management. To deal with the contradiction of agriculture development and water pollution, the trend of increasing paddy area and using amount of fertilizer, pesticide and herbcide in the western Jilin Province should be controlled. Also, the drainage of return flow from paddy should be controlled and return flow should be disposed with ecotechniques by use of the large areas of lakes and mires in the area. Through these measures, the quality of surface water could be protected and the degeneration of ecoenvironment in the area could be contained.
