This study aimed to provide theoretical bases for optimized land use in minority settlements at high altitude. On the basis of forest form map and land use type map (1∶250 000) of Ganzi Tibetan Autonomous Prefecture in Sichuan Province in 2007, this study carried out further analysis and assessment on the landscape pattern and fragmentation degree of Ganzi from the perspective of overall landscape characteristics, area and perimeter of patches, quantity and fractal dimension of patches and so on with the support of geo-info systematical software ArcCIS and landscape structure analysis software Fragstats. The results showed that among all landscape elements alpine meadow and evergreen broad-leaved shrubs take up a larger part as temperate and cool temperate grassland and marsh are scattered with small areas; deciduous and broad-leaved as well as their mixed forest have higher landscape fragmentation degree, on the whole, the fragmentation degree of forest type is higher than that of meadow and shrub; fractal dimensions of landscape components are all small and tend to 1, which indicates that the folded degree of all landscape boundaries are small. 展开更多

Social capital in the form of social resources or social networks is one of the most important livelihood capital of farmers, which can increase the labor productivity of poor households and increase income. It is important to explore the reasons underlying the livelihood strategy choices of farmers from the perspective of social capital under China’s rural revitalization strategy. In this study, the Liangshan Yi Autonomous Prefecture, a povertystricken mountainous area in southwestern China, was selected as the case study area, and multivariable linear regression models were constructed to analyze the influence of social capital on livelihood strategies.The results are as follows:(1) Individual social capital had a positive effect on non-agricultural livelihood strategies. On average, with a one-unit increase in individual social capital, the ratio of farmers’ nonagricultural income to total productive income(Income_Rto) increased by 0.002% and 0.062%,respectively. Collective social capital, with the Peasant Economic Cooperation Organization(PECO) as the carrier, had a negative effect on the non-agricultural livelihood strategies of farmers;on average, with a oneunit increase in PECO, Income_Rto decreased by approximately 0.053%. However, this effect was only significant in the river valley area.(2) The income differences among the different livelihood strategy types were explained by the livelihood strategy choices of farmers. As non-agricultural work can bring more benefits, the labor force exhibited one-way migration from villages to cities, resulting in a lack of the subject of rural revitalization. It is necessary to implement effective measures to highlight the role of PECO in increasing agricultural income for farmers. Finally,based on the above conclusions,policy recommendations with respect to livelihood transformation of farmers and rural sustainable development are discussed. 展开更多

The construction of the market-oriented ecological compensation mechanism in China is complicated system engineering. China's ecological compensation funds are mainly derived from the public finance, lacking market-oriented operation. That not only increases the financial burden of the government, but also leads to the incomprehensive compensation scope. Moreover, China's ecological compensation lacks market mechanism so that it is difficult to set compensation standards and calculate offsets. This paper takes Gannan Tibetan Autonomous Prefecture as an example to analyze the market-oriented ecological compensation system of ethnic minority areas from the perspective of market economy, so as to provide a theoretical basis and a reference point for the establishment of efficient and reasonable ecological compensation mechanism and policies in ethnic minority areas and provide environmental protection for the sustainable development of economy and society of ethnic minority areas. 展开更多

By studying current seedling production in Honghe Hani and Yi Nationality Autonomous Prefecture, tropical and subtropical urban landscape plant production in southwest China was analyzed. Local nurseries total 6.40 km 2 , accounting for 5.1% of total constructed land area in the prefecture, and only 0.02% of the total land area in the prefecture. Application of local plant species in landscape engineering and green coverage ratio lags far behind the indexes of Chinese livable city and indexes of relieving urban heat island effect. By making proper policies and measures, seedling production can be promoted, rare and endanged wild plant species should be fully used to construct garden city, control PM2.5 and protect the living environment. 展开更多

This study takes Gannan Tibetan Autonomous Prefecture as the place of case study and tourists as research objects. From the perspectives of geographical distribution of source tourist markets, Tourist activity behavioral and spatial patterns of Tourists, this study looks into the geographical structure of the source tourists and spatial patterns by geography. The analysis of 341 questionnaires on tourists shows that:(1) The tourism cycle of Gannan is in the development phase, competing with adjacent Aba, and greatly impacted by the substitution effect and shadow effect of Aba.(2) The spatial distribution of tourist sources is concentrated, indicating that Gannan is a regional tourism destination. The temporal distance of tourists is mainly concentrated within the 6-hour traffi c circle.(3) Gannan Tibetan Autonomous Prefecture has already become the composite tourist destination dominated by leisure vacation. The minority folkcustom and special landscape are the most attractive tourism resources. Due to the impact of man-land harmonious lifestyle in the tourist areas, the environmental attitude of tourists is improved, and the transportation and shopping are the most vulnerable links in tourism service in Gannan Tibetan Autonomous Prefecture.(4) The spatial behavior of tourists in Gannan is mainly of single-destination style(52%), Transit leg and circle tour style(7%) as well as circle tour style(41%). The spatial distribution of tourist fl ow in Gannan shows a signifi cant feature "more in the north, less in the south and dependent on National Road". Tourism resources, transport facilities, regional competition and lack of route connecting different ecological units are important causes of the spatial distribution of self-help tourists. 展开更多

The aesthetic perceptions of local residents towards residential landscapes are significant to the protection and sustainable development of regional landscapes, especially in underdeveloped areas with landscape resources of higher aesthetic value. Using Nujiang Lisu Autonomous Prefecture in Yunnan Province as a case study, we conducted questionnaires with 620 local residents and a logistic regression model to determine aesthetic perceptions and factors affecting these perceptions. We found that local residents in Nujiang hold a relatively high perception of their residential landscapes. A majority of respondents, 75.81%, believe their residential landscapes are beautiful. Eight factors were found to influence the aesthetic perception. In direct influential factors, administrative village located in the protected areas and the standard deviation of the elevation around the administrative village have positive influence; distance from administrative village to county town, the ecological environment has changed in recent years, whether tourism development has a negative impact and wish to live in the city have negative influence. In indirect influential factors, both residential house type and have a television at home have positive influence. Based on these results, we discussed relevant policy suggestions to maintain the aesthetic perceptions held by local residents of their residential landscapes and promote the protection and sustainable development of this valuable landscape in Nujiang. 展开更多
