“…Therefore, LUCC has become a core content of worldwide environmental change studies [70,71], and research results have been emerging since the 1990s. In China, Prof. Liu Jiyuan's team has continued to carry out research on national LUCC and achieved outstanding results [57,72], laying a foundation for national and regional research on SLU. In recent years, LUCC research has developed into an independent and interdisciplinary research field: Land Change Science (LCS) [73], and the Global Land Plan (GLP) has organized a land system science research group, forming Land System Science (LSS) [74][75][76].…”

The basic characteristics of mountain areas are that the innate ecological environment is relatively fragile, the acquired ecological environment is severely damaged and degraded, the whole economy and society are still relatively backward, and the degree of sustainable development is relatively low. At present, it has not been seen that land use sustainability evaluation (LUSE) research lasting for many years based on RS and GIS in mountainous provinces. It is urgent to build a suitable, feasible, operable and applicable LUSE system for mountainous regions so as to provide a basic foundation for strategic planning and management of sustainable land use in mountainous provinces. This study integrated “RS and GIS + multi-phase LUCC + LUSE theory and quantitative practical methods” based on mountain provinces, firmly grasped the basic characteristics of mountain areas—the vulnerability of ecological environment, and conducted the study on mountain LUSE. According to the outcomes of RS of land use in the study area in three phases (2000, 2010 and 2020), a comprehensive indicator system is established from the three dimensions of ecological friendliness of land use (EFLU), the economic viability of land use (EVLU) and social acceptability of land use (SALU). Using the Delphi method to determine weights and combining the AHP method and the comprehensive analysis method, this paper quantitatively measures the overall sustainability of land use (OSLU) of 129 counties in Yunnan province in 2000, 2010 and 2020, revealing the spatio-temporal characteristics of the OSLU of Yunnan province and all counties from 2000 to 2020, and aiming to provide a basic and foundation for strategic planning and management of sustainable land use (SLU) in mountainous provinces. The degree of ecological friendliness (DEF), degree of economic viability (DEV), degree of social acceptability (DSA) and degree of overall sustainability (DOS) in Yunnan province and all counties have been significantly improved. Accordingly, the OSLU has been improved to a certain extent, with a 0.66% annual growth rate. It indicates that the development and construction from 2000 to 2020 have significantly improved the OSLU. However, regional differences are large. At present, EFLU, EVLU, and SALU in Yunnan province are not high as a whole. The basic situation reflected that there are obvious deficiencies in EFLU, EVLU and SALU in Yunnan province. Land exploitation and use activities have caused certain influences and the destruction of the ecological environment.

In terms of research methods, the change in land use structure and quantity is analyzed by the land-use transfer matrix [6], the land-use change index [7] land-use degree [8] and so on. Principal component analysis [9], geographical weighting model [10] and random forest model [8] are widely used to explain the driving mechanisms of land use change.…”

Land use change is an essential representation of the interaction between human activities and the natural environment as well as a vital part of global environmental change and sustainable research. Exemplified by the Gansu section of the Yellow River Basin, land-use transfer matrix, land-use change index and principal component analysis are used to study the spatiotemporal evolution pattern and driving mechanism of land use. The results revealed that during the study period, grassland, plowland and woodland are the primary type of land use in the Gansu section of the Yellow River Basin, land use transition was mainly based on the transfer between plowland, grassland and construction land. The comprehensive land use change index was 0.39%, showing a fluctuation trendency of the first rising, then falling and then rising; the individual land-use change index in different land use types was shown in descending order: Construction land > water > plowland > woodland > grassland > unused land. Population structure, economic level, and industrial structure are the main driving factors affecting the change of construction land and plowland area.

“…This comprehensive approach enables the acquisition of 1:100,000-scale land use-type vector data, which is subsequently utilized to generate 1 km grid-based percentage ecosystem type data. Notably, the accuracy of the primary land use types surpasses 90% through rigorous field validation procedures [30,31]…”

The National Key Ecological Function Zones (NKEFZ) serve as crucial ecological security barriers in China, playing a vital role in enhancing ecosystem services. This study employed the theoretical framework of ecological benefits assessment in major ecological engineering projects. The primary focus was on the ecosystem macrostructure, ecosystem quality, and key ecosystem services, enabling quantitative analysis of the spatiotemporal changes in the ecosystem status of the NKEFZ from 2000 to 2019. To achieve this, remote sensing data, meteorological data, and model simulations were employed to investigate five indicators, including land use types, vegetation coverage, net primary productivity of vegetation, soil conservation services, water conservation services, and windbreak and sand fixation services. The analysis incorporated the Theil–Sen Median method to construct an evaluation system for assessing the restoration status of ecosystems, effectively integrating ecosystem quality and ecosystem services indicators. The research findings indicated that land use changes in NKEFZ were primarily characterized by the expansion of unused land and the in of grassland. The overall ecosystem quality of these zones improved, showing a stable and increasing trend. However, there were disparities in the changes related to ecosystem services. Water conservation services exhibited a decreasing trend, while soil conservation and windbreak and sand fixation services showed a steady improvement. The ecosystem of the NKEFZ, in general, displayed a stable and recovering trend. However, significant spatial heterogeneity existed, particularly in the southern region of the Qinghai–Tibet Plateau and at the border areas between western Sichuan and northern Yunnan, where some areas still experienced deteriorating ecosystem conditions. Compared to other functional zones, the trend in the ecosystem of the NKEFZ might not have been the most favorable. Nonetheless, this could be attributed to the fact that most of these areas were situated in environmentally fragile regions, and conservation measures may not have been as effective as in other functional zones. These findings highlighted the considerable challenges ahead in the construction and preservation of the NKEFZ. In future development, the NKEFZ should leverage their unique natural resources to explore distinctive ecological advantages and promote the development of eco-friendly economic industries, such as ecological industry, ecological agriculture, and eco-tourism, transitioning from being reliant on external support to self-sustainability.
