| 1 | Construction of ecological security patterns and ecological restoration zones in the city of Ningbo,China显示文摘Studying an ecological restoration zoning process under the background of ecological security patterns is of great significance to the rapid adjustment and optimization of a landscape pattern.In this study,a remote sensing ecological index and a morphological spatial pattern analysis method were used to assess the quality of habitats and identify ecological sources in the city of Ningbo;ecological corridors,ecological pinch points,and ecological barrier points were extracted by using a circuit theory to construct ecological security patterns and ecological restoration zones.The results indicate:(1)There were 47 ecological sources,and 83 key ecological corridors in Ningbo,and the ecological land area was about 1898.39 km^(2),accounting for 19.89%of the total study area.(2)The ecological source areas were distributed in“one patch and three belts”,and the low-resistance ecological corridors were concentrated in southern Yuyao city,western Haishu district,and central and western Fenghua district;the ecological network in the western and southern regions was dense.(3)There were four types of ecological restoration zones that need to be established,which were prioritized restoration zones,prioritized protection zones,key conservation zones,and general conservation zones distributed hierarchically from inner part towards outside.(4)Ninghai county,Yuyao city,and Fenghua district had large ecological land areas,however,prioritized restoration and protection zones in Ninghai and Fenghua were also large.The analysis results are expected to provide a reference for optimizing a territorial ecological space in a city. | ZHANG Haitao LI Jialin TIAN Peng PU Ruiliang CAO Luodan | 2022 | Journal of Geographical Sciences2022，32，4： | 7 |
| 2 | Spatiotemporal pattern of urban forest leaf area index in response to rapid urbanization and urban greening显示文摘Rapid urbanization and urban greening have caused great changes to urban forests in China. Understanding spatiotemporal patterns of urban forest leaf area index(LAI) under rapid urbanization and urban greening is important for urban forest planning and management. We evaluated the potential for estimating urban forest LAI spatiotemporally by using Landsat TM imagery. We collected three scenes of Landsat TM(thematic mapper)images acquired in 1997, 2004 and 2010 and conducted a field survey to collect urban forest LAI. Finally, spatiotemporal maps of the urban forest LAI were created using a NDVI-based urban forest LAI predictive model.Our results show that normalized differential vegetation index(NDVI) could be used as a predictor for urban forest LAI similar to natural forests. Both rapid urbanization and urban greening contribute to the changing process of urban forest LAI. The urban forest has changed considerably from 1997 to 2010. Urban vegetated pixels decreased gradually from 1997 to 2010 due to intensive urbanization.Leaf area for the study area was 216.4, 145.2 and173.7 km^2 in the years 1997, 2004 and 2010, respectively.Urban forest LAI decreased sharply from 1997 to 2004 and increased slightly from 2004 to 2010 because of numerous greening policies. The urban forest LAI class distributions were skewed toward low values in 1997 and 2004. Moreover, the LAI presented a decreasing trend from suburban to downtown areas. We demonstrate the usefulness of TM remote-sensing in understanding spatiotemporal changing patterns of urban forest LAI under rapid urbanization and urban greening. | Zhibin Ren Yunxia Du Xingyuan He Ruiliang Pu Haifeng Zheng Haide Hu | 2018 | Journal of Forestry Research2018，29，3： | 4 |
| 3 | 方向对比度和区域标准差相结合的图像融合显示文摘小波变换的图像融合方法已成为现今研究的一个热点。但几乎所有的算法都是在小波域不同尺度上分别对高频系数和低频系数进行融合,没有考虑到它们之间固有的相关性。为此,提出了一种基于方向对比度和区域标准差最大的融合新算法,主要特点是在低频部分采用加权因子自适应调节参数融合,以减少边缘模糊,对于高频部分采用方向对比度和局部区域窗口标准差最大值作为高频分量,突出对比度和局域细节,实验表明:融合后影像信息量丰富,地物轮廓清晰可辨,对比度大大加强,空间分辨率得到了提高,最大限度保留了原始影像的光谱信息,是一种可行有效的融合方法。 | 林卉 Ruiliang Pu 梁亮 张连蓬 | 2014 | 计算机工程与应用2014，50，6： | 3 |
| 4 | A review on anthropogenic geomorphology显示文摘With the continuous development of man's ability to reshape naturehuman activities have become the third geomorphologic agent in the modern geomorphological process. Man-made landform is a landform unit characterized by human activities and is a result of synergizing human and nature geomorphologic agents under the physical geographical background. This article provides an overview on the major progresses in research on anthropogenic geomorphology from aspects like the origin of anthropogenic geomorphologyman-made landform agents and classificationman-made landform evolution and its influencing mechanismmap presentation of man-made landformand environmental impact of man-made landforms. In additionin the articlethe future development of anthropogenic geomorphology is forecasted. It is pointed out that future studies on anthropogenic geomorphology should pay more attention to the following directions: construction of discipline system of anthropogenic geomorphologymaterial composition and morphological features of man-made landformsspatial expansion process and development laws of man-made landformsregional disparity and accumulative environmental effects of man-made landformsand environmental management on man-made landforms and comparative analyses of relevant international management policies. | LI Jialin YANG Lei PU Ruiliang LIU Yongchao | 2017 | Journal of Geographical Sciences2017，27，1： | 2 |
| 5 | Ecosystem service valuation of bays in East China Sea and its response to sea reclamation activities显示文摘Ecosystem service values(ESVs)of bays and their response to sea reclamation are of great practical importance for forming bay eco-compensation policy and extension of blue economic space.Based on land use information of bays collected during the period of 1990–2015,the spatiotemporal evolution of ESVs of 12 main bays in East China Sea and their response to sea reclamation activities over the past 25 years were quantitatively analyzed.The analysis results indicate that ESVs of bays in East China Sea showed a continuous downward trend and the whole ecosystem was continuously degraded,in which the degradation degree of ESV in the southern bays was higher than that in the northern bays.Spatial zoning of ESVs of bays in East China Sea was remarkable,showing a continuous downward trend from low-value to high-value zone.Spatial variation of ESVs of each bay was also significant,expanding from a city and from inland to the coast,which suggests that human activities,mainly reclamation,have become main agents for ESV evolution of bays in East China Sea.ESVs of bays have a significant response to sea reclamation,manifested as a significant negative correlation between ESV and reclamation intensity.The correlation in the southern bays was stronger than that in the northern bays,which was caused by different effects of sea reclamation modes on ESV evolution of muddy and bedrock bays.A negative effect of sea reclamation activities on bay ecosystem was hysteretic.Therefore,an attention should be paid to dynamic monitoring and early warning of development status in offshore areas,ecosystem-level reclamation control policy,and coastal wetland reserves planning.Moreover,the spatial coupling mechanism study between bay ecosystem service demand and its service supply capacity should be strengthened to realize systematic regulation of bay ecological security pattern. | LIU Ruiqing XU Hao LI Jialin PU Ruiliang SUN Chao CAO Luodan JIANG Yimei TIAN Peng WANG Lijia GONG Hongbo | 2020 | Journal of Geographical Sciences2020，30，7： | 2 |
