Therefore, this study examines the effects of agriculture and urbanization on water quality, the structure and functional organization of macroinvertebrates of streams in the coastal zone of Cameroon. Nine sampling stations including three per catchment area with different land occupations (agricultural, urban and forest) were selected. Benthic macroinvertebrates were sampled monthly from February to July 2018 and the physicochemical variables were measured simultaneously. The urban and agricultural streams showed highly polluted waters with high nutrient and suspended matter content, whereas the forest stream waters are moderately polluted. In addition, the hierarchical ascending classification indicated a proximity in water quality between the agricultural and forest streams for which the main physicochemical variables did not vary significantly. With regards to macroinvertebrates, the forest watercourse is characterized by the proliferation of pollution-sensitive taxa, high diversity indices and complex trophic structuring, indicating its good ecological status. In contrast the urban watercourse, heavily polluted is characterized by low diversity indices reflecting a simplification of the structure of stands dominated by the pollution-tolerant collector-gatherer stands. The majority of biological indices and functional feeding groups were not significantly different between the agricultural and forest streams, suggesting a less pronounced impact of agriculture on macroinvertebrates. Our results showed that, riparian vegetation even though constituted of perennial crops, reduces the effects of agricultural inputs on streams and promotes the establishment of diversified macroinvertebrate communities.展开更多

Agricultural products that meet various functional needs such as nutrition,health care and safety are increasingly favored by the general public. Se,one of the trace elements necessary for the human body,has begun to be applied and developed in medicine and other life sciences. Developing Se-enriched agricultural relying on Guangxi's unique Se-enriched soil resources is of great significance to enhance people's quality of life,increase the added value of agricultural products,and promote the transformation and upgrading of modern agriculture in the region. Starting with the development status and advantages of industrial development of Se-enriched agriculture in Guangxi,the main problems existing in the current industrial development of Se-enriched agriculture in Guangxi were summarized,and specific countermeasures were put forward in this paper,so as to provide theoretical support for the development of Se-enriched agriculture in Guangxi.展开更多

The policy orientation promoted by the government in agricultural industrialization management is pointed out: formulating a series of macro-management planning to guide and regulate agricultural industrialization operation; fully playing the comprehensive coordinating role of "economic manager"; making and carrying out relevant laws and regulations to normalize the implementation of agricultural industrialization management. To implement the industrial management of agriculture and promote the construction of new countryside, governments at all levels should eliminate the institutional barriers, transform governmental functions gradually and prioritize planning, regulation, service and supervision, changing from merely management to playing the role of market mechanism. Meanwhile, economic, legal and administrative means should be properly adopted to advance the industrial management and the healthy improvement of modern agriculture.展开更多

The agricultural industrial cluster model constituted by core network and supporting network is constructed. Three operation models of this kind of supply chain is described: the model takes wholesale market of agricultural products as the core; the model take pillar industries of agricultural industrialization as core; model takes the chains of retail enterprises as core. The competitiveness of agricultural industrial cluster is researched. The research assumes that the competiveness of supply chain of agricultural industrial cluster is mainly represented to make the agricultural industrial cluster to acquire more capabilities in terms of innovation and knowledge sharing capability, resource allocation capability, agile market adaptability and distinct value creation capability.展开更多

At present, the level of agricultural mechanization in China is promoted steadily; the science and technology are applied to agriculture extensively; the agricultural regionalization layout gradually takes shape; the agricultural industrialization management develops steadily. Be that as it may, the overall quality of farmers is low; the agricultural infrastructure is weak; the agricultural resources are limited; the inputs of agricultural science and technology are short. These hamper the development of modern agriculture. We should implement "industry nurturing agriculture"; through capital support and policy guidance, reform household registration system; connect the fragmented land into parcel; encourage the leading enterprises to develop in rural areas; establish agricultural cooperative organizations; deepen rural financial system reform; quicken the promotion and application of agricultural technology. These measures can effectively promote the development of agriculture, and realize the agricultural modernization in China.展开更多

[Method] By dint of Jianchang climate resources and routine numerical statistics method, the sunlight and temperature changes trend from 1960 to 2009 in Jianchang County were analyzed. [Result] The sunshine hours and sunshine percentages during frost period in Janchang County from 1960 to 2009 tended to decrease. The climate tendency rates were -55.556 h/10 a and -2.39%/10 a respectively, 287 h and 12% of deduction in recent 50 years. There were climate transition in 1981 and 1982. And there were a shortage of 161 h and 7% of sunshine hours and sunshine percentages before and after the transition. The temperature during the frost period generally was increasing. The average temperature, average maximum and lowest temperature tendency rate were 0.386, 0.392 and 0.567 ℃/10 a. There was a growth of 1.93, 1.96 and 2.84 ℃ in recent 50 years. There were temperature transition in 1987 and 1988. The average temperature, average maximum and lowest temperature increased 1.3, 1.2 and 1.7 ℃. In recent 50 years, the sunshine resources during frost period in Jianchang were decreasing, while the thermal resources were strengthening, forming complementary of light and heat. [Conclusion] The study provided climate accordance to the development of local facility agriculture during frost period.展开更多

Benthic macroinvertebrates were sampled monthly from February to July 2018 and the physicochemical variables were measured simultaneously.
