Agriculture is a national basic industries, agriculture is is to determine all issues critical and engaging in other building fundamental premise. However, China's urban-rural income gap is growing. Currently, accelerate rural development has become the party and the country's priorities. Since reform and opening, the city's economic development, but also caused the destruction of the environment, rural development can not repeat the urban development \Rural development must be people in harmony with nature as the theme, adhere to the path of sustainable development. In this paper, sustainable rural development as the goal, in the analysis of rural pollution sources, based on the extracted Dujiangyan watershed rural ecological environment protection mode. This paper consists of five parts, each part of the main contents are as follows: Chapter I: Introduction. First, the account of the background to the study: country attached great importance to urban-rural income gap is increasing and rural environmental degradation, rural ecological environment protection mode to establish not only adapt to the country's development trend, and promote rural economic development, protection of the rural ecological environment . Then, from sustainable development ideas, rural development, ecological agriculture and ecological rural these three aspects of the domestic and foreign research progress. Finally, the introduction of the article research ideas. Chapter II: the rural ecological environment Condition. Rural ecological environment in the text means: including soil, water, air, biological, etc., rural survival and reproduction of the various environmental elements overall. For the rural ecological environment, from the eco-system and the gray box system two aspects of evaluation. Rural ecological environment status quo is not optimistic: the modernization of agriculture pollution, sewage and solid waste not processed, livestock manure pollution levels, pollution of township enterprises prominent urban industrial \In most rural areas, where pollution mostly by agricultural production and farmers living these two aspects caused. Chapter Three: Dujiangyan watershed rural ecological environment protection mode designs. First, the analysis of the Dujiangyan basin profile and characteristics, Dujiangyan watershed rural ecological environment protection mode to establish the foundation. Then, the proposed schema design theory: Agricultural Production pollution can be divided into four categories: fertilizers, pesticides, organic waste and agricultural film, these contaminants can be fertilizer and organic fertilizer, low residual toxicity of pesticides and biological pesticides, fermentation, biodegradable agricultural film materials or techniques used to get the appropriate treatment, these treatments can be summarized as ecological agriculture; farmers' living pollution can be divided into two categories: sewage and solid waste, these contaminants can be carried sewage treatment and garbage disposal to get treatment, these two approaches can be summarized as civilized life. These measures implemented are dependent on the rural population, biogas, sewage treatment, garbage disposal, ecological agriculture, environmental education, quality education, markets and governments that nine major elements, these elements combine to build Dujiangyan drainage areas ecological and environmental protection mode. Next, the proposed Dujiangyan watershed rural ecological environment protection mode evaluation system for convection region has been carried out in rural ecological environment protection project evaluation. Chapter IV: The Anlong project Village. \In the evaluation system under the guidance of the author of the project villages conducted a field survey. The survey used a questionnaire divided into four categories, namely for different groups to investigate. Through the survey results were analyzed, can be found: Anlong project villages in rural ecological environment protection mode is not set up, project sustainability is not optimistic, project participation enormous impact, hardware facilities regions are unevenly distributed, participants age differences larger. To solve these problems, the author proposes three recommendations: increase the hardware number of facilities, building a harmonious atmosphere, focus on brand building. Chapter V: Discussion. We build the rural ecological environment protection mode, the traditional ecological agriculture research extended to include ecological agriculture and civilized life, including eco-rural research, Dujiangyan watershed in rural areas, overall sustainable development provides a good idea, Meanwhile, the model for other similar rural areas, sustainable development also has a certain significance. This deficiency in that: the rural ecological environment protection pattern analysis, tend to nine elements of an independent analysis of their interaction, interaction analysis less; For by the township enterprises produce pollution, pattern did not propose appropriate countermeasures; whole thesis the qualitative analysis, quantitative analysis is weak; pair mode costs and economic analysis less; under investigation time and master the material constraints, the paper Anlong project villages depth of analysis is not enough. Through analysis, we draw the main conclusions are as follows: (a) rural eco-environmental protection Model Construction requires a comprehensive analysis of rural pollution case to complete. Without involving pollution of township enterprises and urban pollution under the premise of the rural areas are the main pollutants: pesticides, fertilizers, organic waste, agricultural film, sewage and solid waste, and only for these pollutants no one left to make the appropriate processing to complete Model. (2) market and government two factors for rural environmental protection modes enormous impact. The countryside is an open system, the input including physical materials, energy, information, policy, and funding, and its output is mainly products and services. This determines in rural areas to carry out any activity that inevitably involves countryside outside factors, so, this article from system theory point of view, the introduction of market and government two external factors. (3) the rural population is a mode enabling factor. Rural population is the mode bearer of hardware facilities can function properly, the problem could be resolved in time, ecological agricultural production and how the quality assurance ...... these problems eventually resolved are dependent on the rural population. (4) economic efficiency is the mode sustainability of the key. Ecological agriculture is the mode key, for most rural population, the agricultural income is their main source of income in rural areas of ecological agriculture, must ensure that the rural population from ecological agriculture gains at least be able to make up model from the common agricultural gains in order to encourage farmers to continue to carry out ecological agriculture. This is characterized by: (a) from the entire rural perspective on rural areas, ecological conditions were analyzed, and the rural ecological environment protection mode. Previous studies focused on agriculture, ignoring the lives of farmers brought a lot of pollution, this article just to make up for this deficiency. (2) operable. This article is an operability can be strong practical article. In the model design process, always consider the rural areas the characteristics and needs of farmers. (3) from the micro to start. This paper analyzes the village as objects presented model also to the village for the implementation of the object. (4) analysis and synthesis method integrated use. Analytical method of the rural sources of pollution are divided into six categories, in order to facilitate research; analytical method of the pollution control measures are divided into nine major elements; using integrated method of the various elements are combined to construct the model. (5) model evaluation system and pattern closely, and to evaluate the system is simple, through farmer surveys to complete, convenient and practical.
