Study On Environmental Quality Assessment Of Beijing Cascades Country Golf Club

In this paper, according to the recent relevant informations and investigations of golf course . the environmental factors affecting the golf course were distributed into biodiversity, pesticide safety, fertilizer security and water security on basis of their different roles and influences to environmental. And by coupling the influencing factors according to the weight, environmental quality evaluation system of golf course was obtained initially, and evaluated the environment quality of Beijing cascades country golf club.The biodiversity of golf course was evaluated by the diversity index of biodiversity . The diversity index of biodiversity formula is D=W1D1+W2D2+W3D3+W4D4. D representation of the diversity index of biodiversity, D1,D2,D3,D4 were representation of Tree layer, shrub layer, herbaceous layer and aquatic plants diversity index(H);(?)W4 were representation of Tree layer, shrub layer, herbaceous layer and aquatic plants weight. The results showed that the biodiversity of Beijing cascades country golf club was very rich(95) which formationed by Tree- Bush - Grass compound community. According to the formula of Single pollution index (?) Pi was representation of Pollution Index, Ci was representation of measured Pollutants, Si was representation of Evaluation criteria pollutants, the classification standards was established initially, and evaluated the application of pesticides and fertilizers to environment of Beijing cascades country golf club. The results showed that only metalaxly residues in soil exceeded slightly and Application of fertilizer on the golf course did not polluted basically.The weights of water security of Beijing cascades country golf club were determined by the grey systemic theory. The synthesize pollution index was got on the basis of formula of Single pollution index (?) The result showed that the total phosphorus and total nitrogen were slightly exceeded the standard. Integrated pollution index was 1>P>0 which meaned that water area was polluted slightly,but also within the scope of environmental self-purification, fish and aquatic life without adverse effects.According to the evaluation results of each content, the four contens, effecting the environment of Beijing cascades country golf club (biodiversity, pesticide safety, fertilizer security and water security), were coupled to E=25%A+25%B+25%C+25%D in the light of same weight ,in which A was representation of biodiversity of golf course, B was representation of pesticide safety, C was representation of fertilizer security, D was representation of water security.The result showed thatThe results showed that the environmental quality index of Beijing cascades country golf club was 87.5,which was better .The result indicated that the day to day maintenance and management of golf course were relatively reasonable.The golf course construction, irrigation, application of fertilizers and pesticides and other measures will not produce pollution to surrounding environment.
