Guangzhou has experienced a decade timber production mainly to the Green Guangzhou, upgrade to this day by a green city began the transition phase of the eco-city forest urban construction. Forest eco-efficiency as the top priority of the urban forest, forest in the city, the city in the forest, Vulcan patronize frequent forest fires has become the biggest killer of ecological forest. How to effectively curb the momentum of the outbreak of forest fires, there is an urgent need to select efficient method of fighting, the maximum reduction of disaster losses, and to protect the safety of urban ecological barrier. 2006, Guangzhou forest fire fighting is a pneumatic fire extinguisher, chainsaw, machete opened isolation belt; No. 2 tools, the traditional method of portable water gun used in combination. Though it was with a certain amount of water pump, but only a few case, over ninety percent of the fire is still using the traditional method. Guangzhou in forest fire fighting in 2006 to comprehensively promote the use of high-pressure pumps, of canned water tankers, communication systems and pumps connected to supporting technical alternative to conventional fire suppression methods, training a large number of comprehensive to the water extinguishing professional team, the actual fire suppression mainly water extinguishing method, the traditional method of extinguishing only with the water pump team to clean up the area do not even have the fire and hillfire weak. Papers at home and abroad forest fire fighting methods and evaluation of the status quo. The guidance system science, economics, forest fire prevention, forest fire ecology and forest fire management science, thorough investigation and study of the socio-economic, physical geography, forest resources and forest fire prevention status quo. The use of qualitative and quantitative analysis method, select a watershed in Guangzhou in 2005 and 2006 as the evaluation object, the use of fighting effects evaluation of the Guangzhou two forest fire suppression method evaluation studies. Qualitative evaluation of the two methods, the use of water fire extinguishing methods compared with the traditional method has the following advantages: ① personnel deployed, high safety factor (2) into a flame speed, fighting ③ extinguished completely, the chances of return fire. low ④ trees survived, ecological restoration fast ⑤ fire inputs low, the benefit-cost ratio higher. Each merits elaboration. In this paper, the comprehensive evaluation index then conducted a quantitative evaluation of the two fighting methods, main contents and conclusions are as follows: (1) of this article is to evaluate the results obtained from the 2005 and 2006 forest fire fighting, collected more than two actual data of species in forest fire fighting methods, evaluation of forest fire suppression assessment indicators: five indicators of forest fires burned area, acreage, direct and indirect economic value loss, the ecological value of the loss amount as the evaluation index, the establishment of forest fire fighting method evaluation index system, and each indicator is given a specific calculation method. (2) by collecting data on forest fires in Guangzhou found that, each year more than 80% of the fire loss, fire caused by about 20%, so select when the fire burned area exceeds the total burned area of ??more than 80% of the fires were evaluated, in line with conditions of a fire two years all 24 games, and according to the provisions of the State Council, the level of division of Forest Fire Prevention Ordinance forest fire, serious forest fires in 2005, 24 games in the main fire burned area of ??over 200 hectares, the rest are ordinary fire 2006 24 major fires only ordinary fire, and the biggest fire burned area of ??not more than 27 hectares, in 2005 burned area in 2006 compared to 8:1. (3) the use of the analytic hierarchy obtained each index weights. First come first through expert investigation method of the judgment matrix, then the weight of each index can be calculated. After expert investigation method, draw weights of indicators of the evaluation system for forest fire fighting methods: forest fires burned area of ??0.238 the injured area to 0.252, and the value of direct economic losses amount to 0.126, and the value of indirect economic losses amount to 0.214, ecological value The loss of an amount of 0.170. (4) The standardized data combined weight calculated years forest fires Composite Index: This selection of the poor standardized method to standardize the original data, the calculated normalized data through a comprehensive evaluation index, calculated the index value of the loss of forest fires . From the results, the the 2005 affected Composite Index 8.9,2006 0.7,2005 years affected Composite Index 2006 ratio 12.5:1. (5) From the burned area in 2005 and 2006, compared to 8:1, while the composite index of view increasing the ratio to 12.5:1, the underlying reasons are as follows: ① single indicator to measure can not fully take into account the fire affect all aspects of the comprehensive index evaluation fires can be more in-depth discussion of the actual, more comprehensive look at the problem. (2) water fire-fighting is a way to cool the affected forest, the high temperature of the trees to reduce and improve the survival rate and reduce the loss of Burned trees. (3) isolated combustible artificial continuous forest areas to isolate plus Burned internal survival rate is lower, making the lowering of plaque in the interaction with the outside world, disaster recovery is slow, and water extinguishing not continuous Habitat isolated and under fire inside the ecological recovery to accelerate in the water \
