“…An appropriate increase in precipitation can increase soil moisture, improve the soil water supply, increase the photosynthesis rate, and benefit vegetation growth. [ 20 ] studied the NPP of the tropical rainforest in Xishuangbanna and showed that precipitation had a threshold effect on NPP. The results of this paper showed that the correlation between precipitation and NPP was positive, while the correlation coefficient between temperature and NPP was negative; that is, the increase in temperature on NPP was mainly shown as inhibition.…”

“…On a global scale, the study focuses on NPP of different vegetation types and its relationship with climate [ 16 , 17 ]. On a local scale, NPP research mainly focuses on forests, watersheds and grasslands, and the influencing factors of NPP are attributed to the comprehensive effect of land use change, temperature, rainfall, topography and other factors [ 18 – 20 ]. [ 21 ] found that the average NPP increased by 52.4 gC m -2 yr -1 from 2000 to 2015 in Ximeng, and artificial woodland played a great role.…”

Net primary productivity (NPP) plays an important role in the carbon cycle of an ecosystem. To explore the impact of unused land development on NPP, this study adopted an improved Carnegie Ames Stanford Approach (CASA) model to analyze the changes in NPP before and after the development of unused land in Tang County, Hebei Province, in 2000, 2007, and 2018. The results showed that, due to the changes in land use types from unused land, forestland, arable land with high NPP values to urban and rural residential land, traffic land with low NPP values, and the changes in precipitation and temperature, the NPP in the study area showed an overall trend of decreasing first and then rising from 2000 to 2018. Before the development of unused land in 2000, the total NPP was 38.45×1010 g C. After the development in 2007 and 2018, the total NPP was 36.44×1010 g C and 41.05×1010 g C, respectively. The NPP of each land type in 2018 was arable land (1046.18 g C m-2) > forestland (464.42 g C m-2) > unused land (356.34 g C m-2) > grassland (343.77 g C m-2) > waters (182.56 g C m-2) > urban and rural settlements (120.86 g C m-2) > traffic land (120.70 g C m-2). The distribution of NPP was generally high in the north and low in the south before and after development. NPP was mainly concentrated in the interval of 300 g C m-2 yr-1–400 g C m-2 yr-1, and the range of NPP change was mostly within 100 g C m-2. The influence of elevation, temperature and precipitation on the spatial distribution of NPP was significant. Elevation and precipitation were positively correlated with NPP, while temperature was negatively correlated with NPP. The increase in NPP mainly originated from the conversion of unused land to forestland and arable land. The loss of NPP was mainly due to the conversion from forestland with high vegetation productivity to a land use type with low vegetation productivity, such as the conversion from forestland to urban and rural residential land. The results can provide references for making reasonable land planning decisions and ecological environment construction.

“…The net primary productivity (NPP) of vegetation is expressed as the difference between the total amount of organic matter generated by the photosynthesis of vegetation in the ecosystem and amount of autotrophic respiration carried out by vegetation [1]. Vegetation NPP represents the carbon sequestration by an amount of vegetation per unit of time and space, directly reflecting the nutrient and energy storage potential of the terrestrial ecosystem [2], and is a key factor for estimating the carbon storage of vegetation.…”

“…Furthermore, different scenarios were constructed to delineate the domains of climate change and human activity. Specifically, the objectives of this current study were (1) to simulate the ANPP using an improved CASA model and explore its spatiotemporal variations; (2) to delineate areas where variations in vegetation are caused by human activities and climate change, respectively; and (3) to quantify the effects of climate change and human activities on vegetation ANPP. Additionally, consideration was given to differences among vegetation types.…”

Contributions of Climatic and Anthropogenic Drivers to Net Primary Productivity of Vegetation in the Mongolian Plateau

et al. 2022

Global warming and intense human activity are altering the net primary productivity (NPP) of vegetation in arid and semi-arid regions where vegetation ecosystems are sensitive to climate change, including the Mongolian Plateau (MP). To deepen the understanding of the dynamics of vegetation and its driving factors on the MP, the actual NPP (ANPP) of the MP from 2000 to 2019 was estimated based on a modified Carnegie–Ames–Stanford Approach (CASA) model. The Thornthwaite Memorial and Guangsheng Zhou models were applied concurrently to estimate the potential NPP of the vegetation, and different scenarios were constructed to evaluate quantitatively the impact of climate change and human activity on the vegetation productivity of our study area. The results showed that the carbon sequestration capacities of various vegetation types in the MP differ, with forest > cropland > grassland > wetland. The NPP increased significantly during 2000–2019. Most areas showed a continuous and stable change in vegetation ANPP, with the current trend in variation mainly reflected in the continuous improvement of vegetation. In general, restoration of vegetation was prominent in the MP, and human activities affected more than 30% of vegetation restoration. The ANPP was positively correlated with temperature and precipitation, the latter of which had a more significant effect. Desertification management, restoration of cropland to forest and grassland, afforestation and reasonable grazing activities were the main human activities performed to restore vegetation. This study is expected to advance the theoretical understanding of ecological protection and sustainable development in the MP.

“…Entretanto, mesmo que não haja elevada diversidade, deve-se observar as características fisiológicas das espécies, pois algumas são caducifólias, semi-caducifólia e perenifólias [21]. Em florestas tropicais com períodos secos sazonais há uma maior quantidade de material depositado sobre o solo em períodos mais secos, sendo isso, uma estratégia de controle de perda de água por transpiração [22,23].…”

Aporte e estoque de serapilheira no Brasil: uma análise bibliométrica da produção científica de 2008 a 2019

A ciclagem de nutrientes é um processo chave na manutenção de florestas tropicais. A importância da serapilheira na ciclagem de nutrientes é um tema relevante e vem se tornando a base de diversos estudos nas últimas décadas. Com o objetivo de realizar uma análise quali-quantitativa sobre os estudos de serapilheira no Brasil, foi realizada uma bibliometria da produção científica no período de 2008-2019. Analisamos 119 artigos, distribuídos em 19 periódicos. O ano de 2015 apresentou o maior número de publicação com 18 artigos. O estado do Rio de Janeiro representou 13,45% da produção cientifica, e o bioma Mata Atlântica concentrou 55,72% das publicações, o que pode estar relacionado à presença das Fundações de Apoio à Pesquisa que mais investem na ciência brasileira. Mais da metade das publicações realizaram pesquisas em apenas um ecossistema. Do total de publicações, 71,4% quantificou o aporte da serapilheira, enquanto 21,9% o estoque. Os maiores valores de massa seca de serapilheira foram registrados no bioma Amazônia, com 8,32 ± 2,57 Mg ha-¹ ano-1 e nos ecossistemas caracterizados como floresta primária, com 8,19 ± 3,27 Mg ha-¹ ano-¹. Para o estoque, os estudos realizados no Cerrado apresentaram as maiores médias, com 7,24 ± 1,98 Mg ha-¹. Os resultados demonstraram que o número de publicações se concentra em determinadas regiões brasileiras. Além disso, percebem os que o maior número de estudos em ecossistemas de plantio monoespecífico e misto pode estar relacionado à importância ecológica e econômica para o Brasil.
