Impact of Land Transition on Landscape and Ecosystem Service Value in Northeast Region of China from 2000–2020

Abstract

Drastic land pattern change has taken place in the northeast region of China, which may have a significant impact on landscape and ecosystem service. Up to now, insufficient renewal of land use patterns may limit the latest assessment of landscape transition and ecosystem service value. Meanwhile, the adaptive ecosystem service value improvement method should be established. To solve this issue, the integrated methodology of land-use change monitoring—landscape analysis—the promoted ecosystem service measurement is established. Results show that: (1) New evidence is observed that the cultivated land in Northeast China has been reduced, with 309,610.33 km2 in 2010 and 309,417.52 km2 in 2020, showing a net change area of −192.82 km2. This is the opposite of the increase of cultivated land compared to the past. (2) Shannon’s diversity index displays an upward trend, with the richer landscape types and higher fragmentation in the whole region. In addition, the contagion index reduced, with a total decrease of 1.93, indicating that the patches distribute intermittently and the agglomeration degree of these patches is weakened. (3) More precise ecosystem service value is assessed, from 2868.39 billion yuan in 2000 to 2814.06 billion yuan in 2020, and the hydrological regulation, climate regulation, and soil conservation play a dominant role in these functions in 2020. The spatial pattern of ecosystem service value is high-rank in the Northwest and Southeast, and low-rank in other directions. This study provides the new results on land change and landscape pattern and creates an improved ecosystem service value assessment method in Northeast China, to provide a more suitable ecosystem assessment application for Northeast China.

Differentiated Impacts of Land-Use Changes on Landscape and Ecosystem Services under Different Land Management System Regions in Sanjiang Plain of China from 1990 to 2020

“…We first compared this result with Northeast China, as the Sanjiang Plain is located in Northeast China. The ESV loss ratio of Northeast China is 1.89%/yr from 2000 to 2020, but specifically 1.54%/yr in 2000-2010 and 0.35%/yr in 2010-2020 [60][61][62]. The data show that the ESV loss rate of Sanjiang Plain is higher 2.32%/yr in 2000-2010 and 0.28%/yr in 2010-2020 than that of Northeast China, respectively.…”

Fiscal Ecological Cost of Land in China: Estimation and Regional Differences

“…In 1997, Costanza put forward the importance of ecosystem service value assessment [37], and the Millennium Ecosystem Assessment (MA) in 2005 tabulated ecosystem service functions as supporting functions, supplying functions, regulating functions, and cultural functions, with reference to previous studies [38]. On this basis, Xie Gao-di established the ecological service value table per unit area of China's terrestrial ecosystem to correct the ecosystem service function, and the research results have been widely used in many studies [39][40][41].…”

A Multi-Scenario Simulation and Dynamic Assessment of the Ecosystem Service Values in Key Ecological Functional Areas: A Case Study of the Sichuan Province, China

“…The assessment of ESV is the basis for implementing ecological protection measures, conducting environmental and economic accounting, and formulating ecological compensation policies [10]. There are two primary approaches for evaluating and predicting an ESV: the method of unit service function pricing and the method of the unit area value equivalent factor [11].…”
