The construction and development of township enterprises plays a key role in promoting the development of rural economy. With the implementation of the rural revitalization strategy, township enterprises develop rapidly, but there are problems in the development process that have a negative impact on the quality of local rural water environment. Rural water environment is related to the health of farmers, the healthy development of agriculture and the sustainable development of rural areas, so it is necessary to predict the water pollution of township enterprises. The application of support vector regression forecasting model to the prediction of water pollution of township enterprises can better predict the water pollution of township enterprises with the characteristics of complexity, nonlinear and small sample. This intelligent forecasting method will help to scientifically prevent the development of township enterprises from having negative impact on the quality of local water environment.

In recent years, with the rapid development of the rural economy, while the living standards of rural residents have been greatly improved, the environmental conditions in the rural areas are not optimistic, and water pollution is one of the most important ones. Therefore, in order to improve the rural ecological environment and promote the task of water pollution control, Shandong Province has issued “the Governance Action Plan of black and odor water in rural areas of Shandong Province”. This article mainly uses “ the Action Plan” as a guide to analyze the current situation of rural black water bodies in Shandong Province and the current problems and related countermeasures, and follow the “comprehensiveness, applicability, economy, long-term effectiveness and safety. According to the black and odorous water problems caused by natural, technological and human factors, we will adopt comprehensive methods such as water purification, dredging, source control and pollution interception[1] to promote the treatment of black and odorous water bodies in rural areas, solve outstanding water environment problems in rural areas, and speed up construction of beautiful and livable countryside.

A framework for characteristics identification and source apportionment of water pollution in the Jinjiang River of China was proposed in this study for evaluation. A total of 114 water samples which were generated between May 2009 and September 2010 at 13 sites were collected and analysed. First, support vector machine (SVM) and water quality pollutant index (WQPI) were used for water quality comprehensive evaluation and identifying characteristic contaminants. Later, factor analysis with nonnegative constraints (FA-NNC) was employed for source apportionment. Finally, multi-linear regression of the absolute principal component score (APCS/MLR) was applied to further estimate source contributions for each characteristic contaminant. The results indicated that the water quality of the Jinjiang River was mainly at the third level (65.79%) based on national surface water quality permissible standards in China. Ammonia nitrogen, total phosphorus, mercury, iron and manganese were identified as characteristic contaminants. Source apportionment results showed that industrial activities (63.16%), agricultural non-point source (16.50%) and domestic sewage (12.85%) were the main anthropogenic pollution sources which were influencing the water quality of Jinjiang River. This proposed method provided a helpful framework for conducting water pollution management in aquatic environment.

Surface water pollution issues are relevant and important. The impacts of polluted waters on the catchment area have both short and long term implications. The negative impact affects both the quality of soils grown in the catchment of plants and agricultural crops, and the health of the population living in the area. From this point of view, the assessment of the environmental and ecological-economic damage caused is relevant. To manage the damage to the environment, it is necessary to conduct balanced economic development and measures to control the quality of surface waters. The methodology developed and proposed in this article for a comprehensive assessment of environmental, economic and environmental damage is aimed at creating and monitoring conditions for economic progress, ensuring and protecting the rights of society and the quality of life.

The poor machinability of titanium alloys results in the serious wear of the rake face of a ball-end milling tool. Previous studies indicated that the mesoscopic geometric characteristics of the tool can effectively improve the wear resistance. Therefore, in this thesis, a milling force model and a milling temperature model of a ball-end milling tool were established to verify the effect of the blunt and negative chamfer tool edges. Setting up a test platform for milling titanium alloy, the influence of mesoscopic geometric characteristic parameters on cutting performance of the ball-end milling tool was analyzed. In addition, based on the support vector regression and genetic algorithm, the optimal mesoscopic geometric characteristic parameters were obtained, which were under the four evaluation indices, such as mechanical–thermal characteristics, tool wear, and surface quality of the workpiece. It was verified experimentally that the tool life of the optimized micro-textured tools with the blunt and chamfer tool edges were improved by 33% and 25%, respectively, and the surface roughness was reduced by 26% and 23%, respectively, which were compared to the non-optimized tools. This thesis provides a reference for improving the processing efficiency and the quality of titanium alloys.

The core objectives for rural development support for the period 2007–2013 are: (1) improving the competitiveness of agriculture and forestry, (2) improving the environment and the countryside, and (3) improving the quality of life in rural areas and encouraging the diversification of economic activity. The Council Regulation (EC) No. 1698/2005 includes an unambiguous targeting of smaller and micro-enterprises to sustain job opportunity in rural areas. For this scheduled period, a minimum funding of 10% of the total EU contribution has been withheld by the Council Regulation for the measures connected with the quality of life and diversification of the rural economy outside agriculture and forestry. In spite of this, the EU Court of Auditors has concluded that rural development policy in Europe is ineffective because it continues to allow member states to adopt a predominantly sectoral approach with the primary focus on the agricultural sector (Special Report No. 17/2006). This paper deals with the possible impact of one RDP measure – the reduction of LFA payments according to farm size. Taking into account the variety of regions in Europe and the different situations at national level, it is difficult to provide a single guideline to solve the problem. Implementation without a deep analysis could lead to undesirable consequences. A specific adjustment to the situation of the given country will be advisable.
