Sustainable Tea Garden Ecotourism Based on the Multifunctionality of Organic Agriculture Based on Artificial Intelligence Technology

There have been “tea-travel” resources combining tea gardens and tourism long ago. Chinese people pay more and more attention to the spiritual consumption demand, but they have been criticized because of their imperfect development. Although many experts and scholars have conducted research on this, they have not obtained valid results. However, with the development of modern science and technology agriculture, the emergence of organic agriculture can undoubtedly contribute to the sustainable development of tea garden ecotourism. Therefore, this article is based on the versatility of artificial intelligence technology and organic agriculture, starting from its definition and functional characteristics, combined with the current situation and development requirements of tea garden ecotourism, and deeply analyzes the sustainable development of tea garden ecotourism, ideas, and models in order to provide a reference for the development of ecotourism in China’s tea gardens. This paper uses the data analysis method, comparison method, questionnaire survey method, and other methods to first theoretically summarize the multifunctionality of organic agriculture and tea garden ecotourism and then takes Lushan Yunwu Tea Garden as an example to investigate the tea plantation area of Lushan in 2019 reaching 150,000 mu. The annual output reaches 20,000 tons, and the annual output value reaches 2.342 billion yuan; the plantation area of tea gardens in the country is expanded to 45.997 million mu in 2019, the output value increases to 25.47 billion yuan, and the sales volume reaches about 2 million tons. Research shows that based on artificial intelligence technology, the sustainable tea garden ecotourism market has broad prospects and good development prospects. The unique regional development model of Lushan Yunwu Tea Garden is worthy of reference for many domestic tea garden ecotourism scenic spots.

Spatiotemporal evolution law and output prediction of construction waste in the People’s Republic of China

Based on the relevant data of construction waste (CW) in the People’s Republic of China (PRC) from 2010 to 2018, this study applied K-means clustering algorithm and grey prediction methods to systematically investigate the spatiotemporal characteristic distribution and provincial clustering of CW in the PRC, and predicted the annual output of CW in the next five years from the scientific perspective. Results showed that the annual output of CW in the PRC displayed an overall trend of “rising first and then falling” and “being high in the middle east and low in the northwest,” and the areas with obvious agglomeration gradually spread from the west to the middle and eastern regions. The law of development was consistent with the goals of the Chinese government to promulgate urban agglomeration development policies, prefabricated building encouragement policies, and CW management regulations. In the next five years, the annual output of CW in the PRC will increase by a small margin. Thus, all aspects of CW resource management should be conducted in a planned and step-by-step manner.

Design of Pre Blasting (Pre-Splitting) in Tan Cang Quarry NO.1 in Vietnam

Nowadays, construction material quarries in Dong Nai Province are exploiting with large quarrying depth, and the annual output could reach to tens of million cubic meters. The blasting frequency could be reached to hundreds of times, so the frequency is the major reason decreasing the cohesion of rock mass. Therefore, the surrounding area of blasting holes is broken, especially the area next to the final border where bench slope angle is not implemented as that of design stage, as well as the back break, also causes fractures on the bench slope, resulting in instability and unsafety due to falling rock. In this paper, the author also wants to introduce the pre blasting and the method to define blasting parameters to increase the stabilization of Slopes in Tan Cang quarry NO.1 in Vietnam.

Methods of estimating reserves of productivity growth

Two levels of the estimation of labor productivity reserves are considered: for lower-level (secondary) subdivisions and a construction enterprise. For secondary subdivisions it is recommended to implement the full-scale approach through interconnected single-factor, multifactor and predictable methods. The ground of these methods is based on corre-lation-regressive models of changes in natural output by types of construc-tion and installation works. For the construction enterprise, the authors have allocated groups of factors that determine the average annual output per worker-production of contract works, their structure, production assets and circulating assets, labor, prime cost and operational management. The foregoing provisions are illustrated by examples based on a large body of statistical information from construction practice.

Produção de serapilheira de duas fisionomias do domínio Cerrado, Gurupi, Tocantins

<p>Objetivou-se verificar a produção de serapilheira de duas fisionomias do domínio Cerrado, sendo uma fisionomia de cerrado <em>sensu stricto</em> (<em>s.s</em>) e outra de mata ciliar, ambas as áreas estão localizadas na Fazenda Experimental da Universidade Federal do Tocantins, <em>Campus</em> de Gurupi-TO. Foram instalados aleatoriamente em cada uma das fisionomias estudadas dez coletores de 1 x 1 m, os quais foram monitorados mensalmente durante o período maio de 2012 a abril de 2013. A produção média de serapilheira total mostrou variação apenas no mês de outubro de 2012 e fevereiro de 2013 com uma produção anual de 1829,31 kg ha^-1 na fisionomia de mata ciliar e de 1349,01 kg ha^-1na fisionomia de cerrado <em>s.s. </em>A fração mais representativa da serapilheira total encontrada nas duas fisionomias estudadas foi composta por folhas que perfazem 63,6% do total de material depositado nos coletores seguido pelas frações material lenhoso, flor e propágulo respectivamente.</p><p align="center"><strong><em>Leaflitter production in two Cerrado types, Gurupi, state Tocantins</em></strong></p><p><strong>Abstract</strong><strong>: </strong>The objective was to verify the leaflitter production of the two Cerrado types, one being <em>stricto sensu</em> Cerrado (s.s) and other riparian forests, both areas are located at the Experimental Farm of the Federal University of Tocantins, Campus of Gurupi-TO. Ten collectors of 1 x 1 m were randomly installed in each of the studied areas, which were monitored monthly during the period of May 2012 to April 2013. The mean litter production showed variation only in the month of October 2012 and February 2013 with an annual output of 1829.31 kg ha^-1 in the riparian physiognomy and 1349.01 kg ha^-1 in the s.s. cerrado. The most representative fraction of Total litter found in the two physiognomies studied consisted of leaves making up 63.6% of the total material deposited in the traps followed by the timber fraction, flower and propagules respectively.</p>

Discrimination for Bidders’ Parallel String Based on the AHP–Fuzzy

Collusion behaviors in the market are divided into three types: rotation, price alliance and compensation bid. Constructing AHP-Fuzzy model evaluates bidders’ parallel string behaviors. It is judged with the aid of grey correlation analysis and fuzzy comprehensive evaluation. Price correlation, price rationality and the annual output value rate of the total assets are taken as influence factors of comprehensive evaluation. Finally, an example proves the correctness and effectiveness of the model.
