Assessment of Value Changes and Spatial Differences in Land Use Based on an Empirical Survey in the Manas River Basin

Transformation of farmland use and driving mechanism in Xinjiang since China’s Western Development Policy

Since the implementation of China’s Western Development Policy, Xinjiang has experienced rapid socio-economic development and significant changes in its land use patterns. As an important factor in agricultural production, farmland is of crucial for realizing the rural revitalization strategy. Based the theoretical mechanisms of farmland use transformation, this study selected five periods of land use and socioeconomic data from 2000, 2005, 2010, 2015, and 2018 to study the spatial and temporal evolutionary characteristics of farmland use transformation in Xinjiang since China’s Western Development Policy. We then explored the driving mechanisms using an optimal geographic detector model based on parameters. The results showed that (1) Xinjiang’s farmland use transitioned toward large scale and multifunctionality, and the transition characteristics are mainly of fluctuating growth type. The spatial transformation and functional transformation characteristics were generally consistent in spatial distribution. (2) There was a spatial agglomeration in the transformation, which was concentrated in the economic zone of the northern slope of Tianshan Mountain, the Yili River Valley and Kashgar region. The concentration of functional transformation of farmland has increased, but the spatial transformation of farmland has weakened. (3) The role of influencing factors on the transformation of farmland use differed with periods. Finally, the study concluded that the functional transformation of farmland in Xinjiang since China’s Western Development Policy is still at the stage of mainly production function. We suggest that the protection of farmland in Xinjiang in the New Western Development period should be achieved by promoting the transformation of the function of farmland. The findings of this study provide decision-making assistance for the management of farmland use in Xinjiang during the New Western Development period and are an effective tool for achieving the goals of sustainable farmland use and agricultural and rural modernization.

A Study on the Gains and Losses of the Ecosystem Service Value of the Land Consolidation Projects of Different Properties in Hubei Province: An Empirical Comparison Based on Plains, Mountains and Hills

In view of the differences of land use structure and ecological environment changes caused by land consolidation projects with different features and landforms, this paper uses the modified ecosystem service value estimation model to quantitatively evaluate the change patterns of the ecosystem service value (ESV) of land consolidation, development and arrangement projects in Hubei Province under plains, hills and mountains to provide a theoretical basis for the ecological transformation of land consolidation. The results show that, compared with the pre-land consolidation period, (1) the total amount of ESV in the land consolidation project areas has increased, whereas the land development and arrangement project areas have decreased. Under the same nature, the growth rate of land consolidation project areas is as follows: hills < plains < mountains, and the loss rate of land development and arrangement project areas are as follows: mountains > plains > hills and hills > mountains > plains, respectively. Under the same landform, the total loss rate of ESV in land development project areas is slightly lower than that in land arrangement project areas. (2) The total amount of ESV in the land consolidation project areas under different natures and landforms of the supply service function shows a decreasing trend, and the total amount of ESV of the adjustment service, support service and cultural service function shows an increasing trend in the land consolidation project areas, whereas the land development and arrangement project areas show a decreasing trend. There is an obvious value transformation process of “ecology for production” in the land development and arrangement areas.

The Functional Value Evolution of Rural Homesteads in Different Types of Villages: Evidence from a Chinese Traditional Agricultural Village and Homestay Village

China’s social and economic development is in a critical period of transition. With the implementation of the Rural Revitalization Strategy, new rural industries and new formats have developed rapidly. Profound changes have taken place in the human–land relationship, population structure, industrial structure, and rural functions in the vast rural areas, which have a huge impact on the function and value of rural homesteads. The functional evolution of rural homesteads has a strong driving effect on the change of function value of the homestead. The functional value of rural homesteads is affected by the social and economic development conditions, location, resource endowment, land use policy, rural land trading market, the development of new industries and new formats, and the evolution of homestead function; different homestead functions have different values, especially in the non-agricultural production function and asset function of the homestead. To revitalize the idle and inefficient use of the homestead and fully manifest its value when the homestead is transferred or withdrawn, it is necessary to scientifically calculate the homestead value according to the principle of “what function is lost and what value is compensated”. This paper adopts basic geographic data, rural land transaction data, and social and economic data, and it uses participatory rural appraisal, the land estimation method, and the comparative analysis method. According to the classic theory of “structure determines function and function determines value” in systems engineering, the equivalent substitution method and market value method are used to measure and compare the functional values of traditional agricultural villages and tourist homestay villages before and after the functional evolution. The results show that (1) the leading functional evolution of homestead landlords is closely related to the level of social and economic development. The change in the functional value of the homestead presents the same law as the evolution of its leading function. (2) The functional evolution of the homestead has a strong driving effect on its value change. The increase in value caused by the functional evolution of homesteads in homestay villages is significantly higher than that in traditional agricultural villages. (3) The functional value of the homestead is affected by the social economy, location, resource endowment, land use policy, rural land trading market, business development, and the functional evolution of the homestead. (4) It is suggested that the state formulates the compensation standard for voluntary and paid withdrawal of homesteads according to the “functional value theory of homesteads”, to reduce the unfair value compensation caused by location differences.
