Perfecting the Market-Oriented Ecological Compensation Mechanism of Ethnic Minority Areas: A Case Study of Gannan Tibetan Autonomous Prefecture

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.

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.

Determining the planting year of navel orange trees in mountainous and hilly areas of southern China:a remote sensing based method

Remote sensing has demonstrated validity in determining the planting year of deciduous fruit trees;however,its effectiveness in ascertaining the planting year of evergreen fruit trees remains unverified.Furthermore,the sources of error associated with using remote sensing to determine the planting year of fruit trees remain unclear.This study investigates several cultivated sweet orange(Citrus sinensis)varieties,which are extensively cultivated throughout subtropical China.We analyzed Landsat time series data from 132 navel orange orchards in Gannan,covering the period from 1993 to 2021.For each orchard,Google Earth Engine was employed to extract three vegetation indices—Enhanced Vegetation Index(EVI),Normalized Difference Vegetation Index(NDVI),and Normalized Burn Ratio(NBR)—for each available date,thereby generating three distinct vegetation index time series.The planting year of navel orange trees was identified based on abrupt changes observed in these time series.The principal sources of error in determining the planting year were investigated using the Wilcoxon signed-rank test,Spearman's correlation analysis,and Kruskal-Wallis H test.Key findings include:(1)Following the planting of navel orange trees,EVI,NDVI,and NBR exhibited fluctuations and a gradual increase over time,peaking approximately 10 to 15 years later.(2)The vegetation index time series derived from Landsat imagery effectively determined the planting year of evergreen navel orange trees in orchards,even within highly fragmented landscapes.Among these indices,NDVI and NBR time series outperformed the EVI time series.Specifically,the average determination errors for EVI,NDVI,and NBR time series were 6.4,1.8,and 2.8 years,respectively.(3)Major sources of error included the methods used to construct the time series,the selection of vegetation indices,and the orchard management practices.Overall,this study provides a viable method for determining the planting year of evergreen navel orange trees in fragmented landscapes and offers insights into factors contributing to uncertainty in planting year determination.
