Results indicated that the percentages of the area of grassland, woodland, basic farmland and orchard to the total productive land area were 44%, 22%, 20% and 14% respectively according to this new land use scenario. Based on the datasets of 197 counties in the Loess Plateau, the estimated forage potential would amount to 104 881 028 ton/a (hay), which can raise 104 881 028 productivity sheep unit/ a. According to the unchanged price in 1999, pastoral gross product value would amount to 52 440.51 million yuan RMB/a, which is as much as 5.3 times of that in 1999 and exceeds the agricultural gross product in 1999 by 14%. In addition, there are ca. 59% of counties whose mean pastoral product value per person would be more than 1 000 yuan RMB/a, while ca. 41% of counties whose mean pastoral product value per person would be less than 1 000 yuan RMB/a. On the other hand, the estimated agricultural gross product on the Loess Plateau would amount to 11 472 2.34 million yuan RMB/a and ca. 46% of the total would come from pastoral industry, 27% from orchid industry, 14% from forestry and 13% from farmland. From the perspective both ecologically and economically, this paper holds that the herbi-vore-based pastoral industry is a promising industry bolstering the ecological improvement and economical development on the Loess Plateau.展开更多

Under CGS, due to high selectivity, livestock exploit grasslands unevenly, over-and under-using specific areas at the same time with negative effects on their conservation. To counteract these effects, a specific policy and management tool(i.e. Grazing Management Plan) has been implemented by Piedmont Region since 2010. The Grazing Management Plans are based on the implementation of rotational grazing systems(RGS), with animal stocking rate adjusted to balance it with grassland carrying capacity. A case study was conducted on alpine summer pastures to test the 5-year effects produced by the implementation of a Grazing Management Plan in grasslands formerly managed under several years of CGS on 1) the selection for different vegetation communities by cattle, 2) the abundance of oligo-, meso-, and eutrophic plant species(defined according to Landolt N indicator value), and 3) forage yield, quality, and palatability. A total of 193 vegetation surveys were carried out in 2011 and repeated in 2016. Cows were tracked yearly with Global Positioning System collars to assess their grazing selectivity, and forage Pastoral Value(PV) was computed to evaluate forage yield, quality, and palatability. Five years after RGS implementation, cow selectivity significantly decreased and the preference for the different vegetation communities was more balanced than under CGS. The abundance of meso-and eutrophic species increased, whereas oligotrophic ones decreased. Moreover, the abundance of moderately to highly palatable plant species increased, whereas non-palatable plant species decreased, with a consequent significant enhancement of the PV. Our findings indicate that the implementation of Grazing Management Plans can be considered a sustainable and effective management tool for improving pasture selection by cattle and forage quality in mountain pastures.展开更多

The pastoral complex, as a new concept and new goal, is a new breakthrough in the thinking mode of rural development. Promoting the construction of pastoral complex is not only an important measure to effectively solve the problems of agriculture, rural areas and farmers, narrow the gap between urban and rural areas, and promote the modernization of the rural and the agriculture, but also a concrete practice to promote the development of rural green economy. First of all, this paper gives an overview of the rural revitalization strategy and the pastoral complex. Secondly, it analyzes the necessity of the construction of Guizhou pastoral complex. And then, considering the reality in Guizhou, it analyzes the constraints of the construction for pastoral complex. Finally, it makes us think upon the measures to the construction of pastoral complex in Guizhou, and put forward some reasonable suggestions.展开更多

In New Zealand some 50% greenhouse gases (GHG) sources are attributed to agriculture and one third is methane from livestock enteric formation. For many years, many researchers have been exploiting the techniques and methods to measure the emission of methane of New Zealand, further more studing the available options to alleviate the methane emissions. Their pioneering work and successful experiences including the determined methods and mitigation strategies are worth learning for scholars around the world. Some of their approaches were not only suitable for New Zealand grazed livestock, but for many other countries, even the animals are intensively bred in pen. The calorimeter/respiration chamber is the most exactly method in present, but it needs expensive equipments and skilled manipulators, so there are still some difficulty in applying this approach extensively in practice. Sulfur hexafluoride (SF6) trace technique is much adopted for grazed livestock evaluating the methane emission, though its veracity was doubted by some researchers, it is still a good option in present for studying the GHG emissions for grazing animals. By measuring the rumen volatile fatty acid (VFA) concentration to estimate the methane emission is a relatively simple approach, it is just only a rough evaluation, and it is unsuitable for exact study, but this method may be used in China for extensively raised ruminant. In present China, the ruminants are fed in an extensively managed state, the diversities of roughage and animals varieties caused difficult to exactly estimate the methane emission. So exploiting the available options is much important for constituting the exhaustive emission inventory. This review just maybe a good reference for researchers to carry out their studies in years and acquired great achievements in methane mitigation area. outline some practical techniques of New Zealand, those this field, after all New Zealand have been persisting many展开更多

This paper identifies cases where pastoral people respond to external pressures and opportunities in positive ways and adapt to changes. We hope that by doing this a framework of pastoral adaptations can be developed. The first part of this paper focuses on impacts of global economic change, which are mostly negative in nature. Through an extensive literature search in geography, anthropology, range management, and development field, the second part introduces cases that we categorize as positive adaptations.展开更多

文摘For the purpose of contributing to the establishment of optimized eco-productive paradigm, a new layout of land use of the Loess Plateau was carried out and the associated forage potential was estimated. Results indicated that the percentages of the area of grassland, woodland, basic farmland and orchard to the total productive land area were 44%, 22%, 20% and 14% respectively according to this new land use scenario. Based on the datasets of 197 counties in the Loess Plateau, the estimated forage potential would amount to 104 881 028 ton/a (hay), which can raise 104 881 028 productivity sheep unit/ a. According to the unchanged price in 1999, pastoral gross product value would amount to 52 440.51 million yuan RMB/a, which is as much as 5.3 times of that in 1999 and exceeds the agricultural gross product in 1999 by 14%. In addition, there are ca. 59% of counties whose mean pastoral product value per person would be more than 1 000 yuan RMB/a, while ca. 41% of counties whose mean pastoral product value per person would be less than 1 000 yuan RMB/a. On the other hand, the estimated agricultural gross product on the Loess Plateau would amount to 11 472 2.34 million yuan RMB/a and ca. 46% of the total would come from pastoral industry, 27% from orchid industry, 14% from forestry and 13% from farmland. From the perspective both ecologically and economically, this paper holds that the herbi-vore-based pastoral industry is a promising industry bolstering the ecological improvement and economical development on the Loess Plateau.

文摘Over the last decades, the reduction of manpower for herd management has led to an increase of continuous grazing systems(CGS) in the Italian Alps, which allow cattle to roam freely. Under CGS, due to high selectivity, livestock exploit grasslands unevenly, over-and under-using specific areas at the same time with negative effects on their conservation. To counteract these effects, a specific policy and management tool(i.e. Grazing Management Plan) has been implemented by Piedmont Region since 2010. The Grazing Management Plans are based on the implementation of rotational grazing systems(RGS), with animal stocking rate adjusted to balance it with grassland carrying capacity. A case study was conducted on alpine summer pastures to test the 5-year effects produced by the implementation of a Grazing Management Plan in grasslands formerly managed under several years of CGS on 1) the selection for different vegetation communities by cattle, 2) the abundance of oligo-, meso-, and eutrophic plant species(defined according to Landolt N indicator value), and 3) forage yield, quality, and palatability.

Five years after RGS implementation, cow selectivity significantly decreased and the preference for the different vegetation communities was more balanced than under CGS. The abundance of meso-and eutrophic species increased, whereas oligotrophic ones decreased. Moreover, the abundance of moderately to highly palatable plant species increased, whereas non-palatable plant species decreased, with a consequent significant enhancement of the PV. Our findings indicate that the implementation of Grazing Management Plans can be considered a sustainable and effective management tool for improving pasture selection by cattle and forage quality in mountain pastures.

文摘Urbanization,often coupled with industrialization,is generally considered as a boost for improving livelihood as well as alleviating ecological pressures of the rural areas.However,this experience needs to be tested in less industrialized areas,particularly where the urbanization is driven by non-economic factors such as urban public services and relevant government policies rather than employment opportunities.Taking two villages on the Qinghai-Tibet Plateau as examples,through the field investigation by using semi-structured questionnaires and in-depth interviews,and statistical data analysis,we explored the impacts of urbanization on migrants’livelihoods and the ecological conditions of their original village rangeland.We found that the disposable income and savings of emigrant households were less than the stay households,which might be correlated to the limited employment due to the lagged industrialization in the local township,and the mismatch between their traditional labor skills and the demands of urban services.Their home-village rangeland overuse was not alleviated since the increasing grazing pressure caused by the stay households,though the emigrant households intended to decrease the number of livestock on their home pasture.We concluded that the urbanization misaligned with local industrialization may fail to improve migrant livelihoods and local ecological conditions in less industrialized areas.Our research supplements the previous urbanization theory by highlighting the non-industrialization driven urbanization,and is particularly pertinent for the transitional countries worldwide.

Pastoral husbandry is the basis of animal husbandry in Xingjing Animal husbandry in Xingjing Uygur Autonomous Region is supported by the some57 million ha natural rangeland (Commission for Integrated Servey of Natural Resources(CISNAR), 1989). The rangeland provides feeds for the 33 million heads of grazing animals(48.698 million sheep units) in the region. Natural rangeland takes about 35% of the

文摘The aim of this paper was to give a basic understanding of studies on methane emissions of New Zealand, as we know the agriculture of New Zealand is pastoral farming, most livestock animals are grazed in pasture, and quantities of methane were released from the digestive tract and animals excreta. In New Zealand some 50% greenhouse gases (GHG) sources are attributed to agriculture and one third is methane from livestock enteric formation. For many years, many researchers have been exploiting the techniques and methods to measure the emission of methane of New Zealand, further more studing the available options to alleviate the methane emissions. Their pioneering work and successful experiences including the determined methods and mitigation strategies are worth learning for scholars around the world. Some of their approaches were not only suitable for New Zealand grazed livestock, but for many other countries, even the animals are intensively bred in pen. The calorimeter/respiration chamber is the most exactly method in present, but it needs expensive equipments and skilled manipulators, so there are still some difficulty in applying this approach extensively in practice. Sulfur hexafluoride (SF6) trace technique is much adopted for grazed livestock evaluating the methane emission, though its veracity was doubted by some researchers, it is still a good option in present for studying the GHG emissions for grazing animals. By measuring the rumen volatile fatty acid (VFA) concentration to estimate the methane emission is a relatively simple approach, it is just only a rough evaluation, and it is unsuitable for exact study, but this method may be used in China for extensively raised ruminant. In present China, the ruminants are fed in an extensively managed state, the diversities of roughage and animals varieties caused difficult to exactly estimate the methane emission. So exploiting the available options is much important for constituting the exhaustive emission inventory. This review just maybe a good reference for researchers to carry out their studies in years and acquired great achievements in methane mitigation area. outline some practical techniques of New Zealand, those this field, after all New Zealand have been persisting many

文摘Environmental degradation and other socio-economic problems are too often discerned in contemporary pastoral systems in the wake of global economic change. This paper identifies cases where pastoral people respond to external pressures and opportunities in positive ways and adapt to changes. We hope that by doing this a framework of pastoral adaptations can be developed. The first part of this paper focuses on impacts of global economic change, which are mostly negative in nature. Through an extensive literature search in geography, anthropology, range management, and development field, the second part introduces cases that we categorize as positive adaptations.

文摘[Objective] The paper was to study the adaptability of Australian Merino sheep in the alpine pastoral areas. [Method]Through introduction of Australian Merino sheep for hybridizing with Gansu alpine fine wool sheep,the improvement effect of offspring was observed. [Result]The introduced Australian Merino sheep had good adaptability in the alpine pastoral areas with good hair quality,strong cold resistance and disease resistance,and they could grow and reproduce healthily in the alpine pastoral areas. The application effect of the ram was outstanding,showing large breeding amount,high conception rate and survival rate.[Conclusion]The improvement effect of offspring of Australian Merino sheep and Gansu alpine fine wool sheep was significant,and the growth performance was improved greatly.
