Poyang Lake Ecological Economic Zone has large forest area, so it's very important to construct prevention forest fire disaster system. This paper presents an algorithm for prevention forest fire disaster based on digital image processing technology. The algorithm distinguishes the realtime forest video by smoke and fire. To determine whether there are some suspicious area in the image in the spatial domain by judging the color properties of smoke and fire through Clustering Algorithm. If it detects any suspicious circumstances, then fixes ccd and detects the suspicious areas in the time domain. In this step, firstly get the initial detect results by wavelet decomposition , then use the k-means clustering algorithm for the spread detection of smoke. Experimental results show that the algorithm is ideal for the experimental video. It alarms before the fire disaster occurs to avoid major fire disaster, which protects the forest resources in the Poyang Lake Ecological Economic Zone.

BACKGROUND Indonesia forest fire in 2015 emitted a huge amount of pollutants into the air. This study was aimed to assess the health consequences of forest fire smoke in healthy residents in Riau during forest fire disaster in 2015. METHODS This cross-sectional study was performed in healthy residents who lived in Pekanbaru, Riau Province, Sumatera, for at least 6 months during forest fire disaster in 2015, and data were taken in October 2015. Questionnaires consisting of respiratory and non-respiratory symptoms were collected. Lung function was assessed by spirometry (MIR II Spirolab™ spirometer, Medical International Research, Italy) and exhaled carbon monoxide (CO) was assessed using piCO+ Smokerlyzer®. Heart rate at rest and oxygen saturation in the room air were measured using Onyx 9591 Pulse Oximeter®. RESULTS A total of 89 subjects were mostly female (75.3%), housewife (37.7%), nonsmoker (86.5%) with mean age of 38.9 years old. The non-respiratory and respiratory symptoms were reported in 84.7% and 71.4% subjects, respectively. Lung function was impaired in 72.6% subjects, mostly with mild obstruction and mild restriction. Exhaled CO was highly detected over normal values (mean [standard deviation] = 32.6 [9.97] ppm) with predicted carboxyhemoglobin (COHb) of 5.74 (1.56). CONCLUSIONS Forest fire smoke exposure increased the respiratory and nonrespiratory symptoms among healthy individuals, which showed impairment in lung function, exhaled CO, and predicted COHb. Long term health effects on healthy individuals exposed to forest fire smoke warrant further evaluation.

Based on statistical yearbook data in Nanchang city, this paper applies a calculation mode of ecological footprint to conduct calculation and analysis on the ecological footprint, as well as bearing capacity of Nanchang city-the core city of Poyang Lake Ecological Economic Zone from the year 2005 to 2009. According to some research, the average ecological footprint of Nanchang city in recent five years is 1.974879hm2/cap, the average ecological bearing capacity is 0.224917hm2/cap, and the average ecological deficit is 1.749962hm2/cap.Regional eco-environment is in the condition of unsustainable development. This paper also makes an analysis on the intensity of ecological footprint and ecological efficiency in Nanchang city. By taking these as a foundation, this paper puts forward strategies and suggestion to reduce ecological deficit of Poyang Lake Ecological Economic Zone and achieve sustainable development in this zone.

This paper thinks that the reasons for ineffective management of environmental performances of Party and government leaders of the county and municipality in Poyang Lake Ecological Economic Zone are that the leaders lack concept of sustainable development, have unclear understanding of purpose of performance evaluation, do not want to discover shortcomings, the evaluation subjects have serious thought of officialdom standard and deeply rooted thought of ruling by people, and the evaluation information is hard to collect and performance management guarantee system is incomplete; this paper provides measures including improving understanding of importance of performance management of county and municipal leaders in Poyang Lake Ecological Economic Zone, constructing diversified evaluation subjects for environmental performances of the leaders, making evaluation indicators in a scientific way, using evaluation results comprehensively, improving basic guarantee system of performance management and cultivating nice performance management culture.
