Abstract： Chinese Academy of Sciences (CAS) is the initiator and practitioner of poverty alleviation by science and technology in China. CAS undertook the task of poverty alleviation in four poverty-stricken counties, including the Kulun County of Inner Mongolia, Huanjiang County of Guangxi, Shuicheng County and Liuzhi County of Guizhou. In recent years, CAS has supported the industrial development by deploying demonstration projects, constructed a science and technology poverty alleviation network serving the development of poverty-stricken areas. In the evaluation in 2018 organized by the Poverty Alleviation Office of the State Council, CAS is in the top rank.

Abstract： Poverty alleviation or mitigation through science and technology is one of the strategies implemented in China. Grassbased Livestock Husbandry aims to develop sustainable and profitable ruminant farming systems and is an attractive and effective countermeasure for poverty alleviation in grasslands of China. Our survey indicated that 152 counties in the grassland region are in poverty, representing 56.7% of the total 268 counties. Hence, grasslands are the regions where the “hard core” poverty populations reside. As a pilot initiative, Chinese Academy of Sciences has launched projects in the grasslands in the north and the moutain meadows in the south to couple forage cultivation and processing with husbandry of elite local livestock breeds by improving the efficiency of converters of feed to products, and the projects have substantially helped local people increase their household incomes. Nationwidely, the grassland occupies more than 40% of the total national land area, hence the sustainable development of grass-based livestock farming systems could play a central role and have great potential in poverty alleviation.

Abstract： “Scientific achievements are inseparable from spiritual support. The academic spirit is the precious wealth accumulated by researchers and engineers in long-term academic career.” In the 1980s, Chinese Academy of Sciences (CAS) launched Huanghuaihai Innovation Campaign of agricultural science and technology for the reclamation of saline-alkali land. The Campaign successfully improve the overall production capacity in the North China Plain. The Huanghuaihai Spirit, emerged in this multidisciplinary and cross#2;field large-scale scientific and technological campaign, is not only the precious spiritual wealth of CAS, but also an important source of strength for achieving a substantial increase in grain production. In the new era, facing the higher requirements of the national food strategy and the paramount challenge of “protecting and making good use of the black soil”, we must further inherit and carry forward the Huanghuaihai Spirit, take a pragmatic and responsible attitude to solve problems of agricultural production, and build an intelligent agricultural technology system to support the sustainable development and use of black soil contribute to national food security, and promote rural revitalization.

Abstract： With increasing awareness of balanced and healthy diet, the demand for ruminant products has been drastically increasing in China over the past decades. Grass-based Livestock Husbandry (GLiH), a new paradigm for agricultural restructuring and sustainable development, is highly encouraged to meet such demand. Yet, the country’s own production cannot self-support the demand, as envisaged by the soaring import of both red meats and forage products, albeit half of the nation’s cereal production is devoted to animal feed and forage crop production area amounts to 12 million ha. With the affluent population and limited arable land, China is facing challenge to explore possible land areas for GLiH development. We argue that one of the effective ways is to transform the lowand middle-yield fields, which account for over 70% of the cultivated lands, into forage crop production. Our analysis indicated that cultivation of forage crops could avoid the risks of low yield and low economic returns frequently occurring for cereal production on such lands. Furthermore, a forage-cereal rotation cropping system can significantly increase dry mass production, reduce the incidence of pest and disease damage, and ameliorate soil physical and chemical properties by improving soil organic matter, soil fertility and reducing salt and alkaline constraints. Three scenarios have been projected for the potential of the exploitation of low- and middleyielding land for livestock production, and the amount of the red meat production is estimated to be 17.98, 21.58, and 26.98 million tons, respectively, which are 1.6, 1.9, and 2.4 times of the current production nationwide. A case study for Shandong Province is further presented, demonstrating that exploring the saline-alkali land at the Yellow River Delta for forage crop production could substantially alleviate the shortage of forage supplies and optimize the agricultural infrastructure of the province.

Abstract： National major demand and social and economic development are the direction and drive force of scientific and technological innovation. In turn, scientific and technological innovation promotes economic development and social progress, and such innovation is new motive force to promote alleviation of poverty. According to the current situation of crude protein feedstuffs and the development situation of animal husbandry in China, the Institute of Botany, Chinese Academy of Sciences has bred a new hybrid paper mulberry with fast growth, high yield, and high quality, and puts forward the industrial development model of “replacing grain with trees, planting and raising circulation”, which effectively meets the feed demand of poor areas and promote the development of animal husbandry in poor areas. This paper analyzes the progress of paper mulberry poverty alleviation in Heze city of Shandong Province, and discusses the opportunities, problems, and countermeasures faced by the industry poverty alleviation of paper mulberry.

Abstract： In order to improve the efficiency of querying and retrieving models from the enterprise model library, a process similarity algorithm based on the edit distance of transition graph is proposed. Firstly, the concept of the transition graph and its generation method are given. Secondly, the concept of the length of the edge is proposed. The cost of deleting and inserting the edge is determined by the length of the edge. Based on this, the graph editing operation and its cost are defined, and the node matching algorithm is used to calculate the minimum graph editing distance. Then, the similarity concept and calculation method of the two process models are given. Finally, the correctness of the algorithm is verified and the seven similarity properties are satisfied, and the editing distance of the transition graph is verified to satisfy the four distance properties.
