Combined with the sample monitoring of our research and the previous studies of algae growth kinetics,the total algae biomass of Xinyun Lake that can been gathered and removed was fast estimated as 1218800m3/a. Based on the research work about the result of organic fertilizer from algae paste, the internal pollution load reductions of COD, NH4-N and available phosphorus were estimated as 13163.04t, 1018.91t and 146.26t, respectively, in 2012. At last, the environmental benefit, economic benefit and social benefit of organic fertilizer from algae were analyzed, and all of them were very significant.

To support urban sustainable development, cities need innovative green logistics solutions to meet the needs of economic development. Crowdshipping is regarded as a promising sustainable freight solution. This article aims to assess the feasibility of implementing intercity express crowdshipping using private vehicle traveling. The crowdshipping carrier, who drives his or her private vehicle and travels on the intercity route, carries out the express delivery task between the regional cargo center and the dispatch center along the route. The feasibility assessment covers three parts. First, face-to-face interview and stated preference survey are used to investigate the willingness and preferences of express companies and car owners to participate in crowdshipping activities, respectively. Then, it calculates the environmental benefit and economic benefit brought by the crowdshipping mode in comparison with the traditional mode. The results show that the express companies are willing to pay 30 yuan for each car participating in the crowdshipping activities, and there are considerable numbers of car owners to support this crowdshipping activity, and this crowdshipping activity could bring positive impacts on environment as well as corporate economics. It is hoped that the research could enrich the knowledge of the development of green logistics.

Soil quality assessment is an important means to demonstrate how effective land consolidation is. However, the existing assessment system is not sufficient to reflect actual soil quality. So, the purpose of this study is to integrate abiological and biological indicators into a comprehensive assessment to evaluate the paddy soil quality under different land consolidation practices. Soil samples were collected from 35 paddy sites under different land consolidation practices including land merging, land leveling (LL), ditch construction (DC) and application of organic fertilizer (AO). A total of 10 paddy sites were selected under conventional tillage (CT) from non-land consolidation area as a control group in Y county, China. The results indicated that soil organic matter (OM), total nitrogen (TN), available phosphorus, bacterial functional diversity (BFD), bacterial and fungal abundances were significantly improved. Fields under LL, among all the land consolidation practices, might still face the risk of land degradation caused by low TN, OM and microbial diversity. High microbial biomass, BFD and OM were significantly higher in fields under AO in nutrient cycle. According to the results of comprehensive assessment, the samples with severe heavy metal contamination and low microbial diversity were generally concentrated in CT. These results indicated that land consolidation was an efficient technique to improve soil quality and could achieve higher quality of agricultural products.

The evaluation of economy benefits of small watershed warping dams system program mainly includes foundation benefit, economic benefit, ecological benefit, social benefit on project construction. The thesis takes this small watershed planning scheme 30- year computation time as object of study ,on its soil conservation benefit, storage benefit, planting benefits and rationalities irrigation benefit, block mud benefit, economic indexes such as flood protection benefits were analyzed and calculated ,for dam system planning scheme of the economic rationality assessment provides evaluation basis. Using natural "catch-basin" concept, the people of loess plateau created warping dam whose role is storing muddy and releasing clearing, intercept sediment and silting farmland, which is a kind of soil and water conservation engineering measures. Since liberation, in the middle Yellow River area has built more than 110,000 warping dams, exceeding 0.3million hm2 place has been silting into dam land and accumulated retard mud 2.1 million tons. Since 1990s, in order to give full play to the operation safety and overall benefit of warping dams, which has formed the construction concept of dam is "in tributaries as skeletons, small watershed as a unit, matching key dam, small and middle warping dams to construction the dam system of gullies"[1]. Further assure the operation safety and the overall benefit of warping dams, which has been brought into full play. A watershed which is in order to limitation of control the flood and sediment to realize the long-term goals of soil and water conservation. Through the field survey and measurement, selected the dam system layout scheme , determinded the engineering construction scheme of the dam system of the river basin, dam system altogether layout 5 key dam (including 3 seats new dams , 2 seats old dam which is need reinforcement ) ,15 seats small and middle warping dams ,and the project under construction will last for 3 years. Basis to the specification requirement, we need evaluation analysis the planning scheme for engineering benefit. Dam system’s engineering benefits include foundation benefit, economic benefit, ecological benefit and social benefit. Basis to the specification requirement, engineering planning after the project implementation produced by the foundation and economic benefit emphatically analyzes, ecological and social benefits are briefly analyzed[2].

Trichoderma spp. is a cosmopolitan group of soil fungi which plays a remarkable role in stimulating plant growth after interacting with plant roots and has good application prospects in intensive agriculture. In this study, rice straw and amino acids improved the population of Trichoderma guizhouense NJAU4742 under solid-state fermentation and helped us develop a new type of organic fertilizer. The effects of this biological organic fertilizer were evaluated in the growth of peppers (Capsicum annuum L.) for two seasons under sandy and mountain soils. In the first season, the yields in T6 (0.06% solid fermentation products in soil) and AT6 (added 0.06% solid fermentation products and 1% amino acid organic fertilizer in soil) treatments were increased by 41.8% and 52.3% in sandy soil and by 51.6% and 46.5% in mountain soil, respectively, compared with chemical fertilizer. During the second season, the same trend was obtained in both sandy and mountain soils. Soil peroxidase activity (125.2 μmol·g−1 dw), urease activity (58.7 μmol·g−1 dw) and invertase activity (13.11 mg·g−1 dw) reached their highest levels in biological organic fertilizer compared to the treatments with chemical fertilizer and solid fermentation products. Redundancy analysis showed that crop yield was positively correlated with enzyme activities, soil organic carbon, total nitrogen, and available phosphorus. Thus, we demonstrated that NJAU4742-enriched biological organic fertilizer could accelerate the transformation of nutrients and promote pepper growth.
