Ecosystem and Driving Force Evaluation of Northeast Forest Belt

Abstract

The ecosystem in the Northeast Forest Belt (NFB) can provide various ecosystem services, such as soil conservation, habitat provision, water conservation, and so on. It is essential for maintaining the ecological environment in Northeast China and the entire country. In the face of increasingly severe environmental problems, the comprehensive and accurate evaluation of ecosystem conditions and their changes is significant for scientific and reasonable recovery and protection measures. In this study, the NFB was taken as the research area. The spatio-temporal changes in ecological quality from 2005 to 2015 and the main driving factors behind them were analyzed by constructing the comprehensive ecosystem evaluation index. The results showed that: The landscape types of the NFB were mainly forest, cropland, and grassland. And the better ecological environment of the NFB was mainly distributed in the south of Changbai Mountains (CBM), the middle of Lesser Khingan Mountains (LKM), and the northwest of Greater Khingan Mountains (GKM). In contrast, the northeast of CBM, the southwest of LKM, and the edge of southern GKM were relatively poor. During 2005–2015, the ecosystem in the NFB was in a relatively good state as a whole, showing a steady-to-good development trend. However, more attention needed to be paid to some areas where degradation still existed. Land use/cover, climate (annual average rainfall, etc.), and human disturbance were potential factors affecting ecosystem evolution in the NFB. This study aims to provide an effective scientific basis and policy reference for the environmental protection and construction of the NFB.

Increase in precipitation and fractional vegetation cover promote synergy of ecosystem services in China’s arid regions—Northern sand-stabilization belt

“…In addition, trade-off and synergy of multiple ecosystem services are also hot research topics at present, but the research mainly focuses on farmland, wetlands, oceans, cities, and other ecosystems. Especially ecosystems that can generate economic benefits, such as farmland and forests (Johns et al, 2014;Loomis and Paterson, 2014;Song and Deng, 2015;Malekmohammadi and Jahanishakib, 2017;Richards and Friess, 2017;Liao et al, 2022). Furthermore, our literature review found that few scholars, such as Fensholt et al (2012) and Wen et al (2019), have focused on the assessment of ecosystem services in arid and semi-arid regions, especially studies in megaregions.…”

Spatial Patterns and Associations of Tree Species in a Temperate Forest of National Forest Park, Huadian City, Jilin Province, Northeast China

“…The Korean pine broad-leaved mixed forest is the climax vegetation type of Northeast China and is widely distributed in the temperate forests of the region. The ecosystem in Northeast China is of paramount importance due to its large biomass, high biodiversity, and complex community structure [29][30][31]. Previous studies on the distribution of key species in these forests, especially on the northern slope of Changbai Mountain, have used various methods, including χ 2 tests, variance/mean ratio tests, mean square zone tests, and covariance analyses, with mixed results [32].…”

Consistent Changes in Land-Use/Land-Cover in Semi-Arid Areas: Implications on Ecosystem Service Delivery and Adaptation in the Limpopo Basin, Botswana

“…Moreso, the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) provides a platform for governments to improve the interface between science and policy on issues of biodiversity and ecosystem services [11]. Nonetheless, the diversity of landscapes, climate, ecosystem services, cultures, social values, legislation, and the state of development render different land-use and/or land-cover types to be of varying importance to local people [12].…”

“…Liao et al found that land use/cover, climate (annual average rainfall, etc. ), and human disturbance are among the key factors affecting ecosystem service provision in their study of the Northeast Forest Belt in China [12]. Another study by Biratu et al evaluated the impact of landscape management scenarios on ecosystem service values in Central Ethiopia and found that cultivated land increased by 22% under the business-as-usual (BAU) scenario, whereas forest, water body, wetland, and shrubland were reduced [3].…”
