More and more ports appeared along China’s coastline, which destroyed natural coastline and coastal landscape. Some of them are inefficiency operations. It is important to evaluate operational efficiency of ports to reveal their position in regional competitive environment. In this study, high spatial resolution satellite remote sensing images were used to monitor ship number and plane area. The port-use prosperity index(PUI) was subsequently proposed to quantitatively describe port-use business and reveal port-use efficiency. The PUI was applied to six ports around the Bohai Sea, China. The number, scale, and plane of ships docked in these ports were easily monitored by the high spatial resolution satellite remote sensing images, and the PUI was calculated using a ship’s total plane area and length of docked coastline. The PUI is an objective and practical index for evaluating port-use efficiency. It can be used to compare differences in port use and indicate temporal port-use dynamics. The PUI values of Jingtang and Tianjin Ports were the highest(17.75 and 14.14, respectively), whereas that of Yantai Port was the lowest(8.31). The PUI values of the remaining ports were 9.0–10.70. A linear relationship existed between port throughput and PUI in the studied ports. This can forecast port throughput by monitoring and calculating PUI based on high spatial resolution satellite remote sensing images.

In China, promoting the development of coastal areas has been included in a series of national strategic development *** the same time, many marine environmental problems have been associated with the rapid development of coastal sea use. In order to quantify the impact of human activities on the coast, the characteristics of coastlines and near-shore sea use of Liaodong Bay, Northeast China, were first classified using multi-source, remotely sensed imagery using automatic or semi-automatic extraction methods for five periods between 1993 and 2015. Sea use dynamics and coastline dynamics resulting from human activates were analyzed. Results showed a significant trend of continuous growth in sea use and a progressive increase in the total length of artificial coastline, but a noticeable loss of natural coastline during the five periods. Reclaimed land and enclosed areas were the main types of sea use. Most coastal human activities were distributed in the northern part of the bay. In recent years, rapid industrialization and urbanization in China's coastal areas have promoted large-scale land reclamation. Accordingly, the observed coastline changes during each period had a close relationship with coastal development and sea area utilization. Based on marine functional zoning(MFZ), the sea use carrying capacity was evaluated by means of indexes to describe human exploitation of the marine and coastal environments in the bay. This showed that the intensity of coastal utilization in Liaodong Bay has increased year-on-year. Sea use carrying capacity reached a ‘critically loaded'state by 2008 and was ‘overloaded' by 2015.

景观格局和生态过程是景观生态学研究的重要内容,但是很多研究只重视景观格局的研究,而忽略了生态过程的研究。文章针对水土流失这一重要生态过程,提出了基于水土流失过程的景观坡度指数和景观空间负荷对比指数,并对黄土高原泾河流域15个子流域的景观格局进行了分析,认为泾河流北部各子流域主要以水土流失的"源"景观为主,景观坡度指数大,空间负荷指数小,水土流失风险大;流域南部各子流域上游以"汇"景观为主,坡度指数大,中下游以"源"景观为主,景观空间分布不均衡,存在一定的水土流失风险;流域东部局部子流域主要以水土流失的"汇"景观为主,"源"景观相对较小,"源"-"汇"景观空间分布均衡,水土流失风险小。

根据国产资源三号(ZY-3)卫星遥感影像光谱特征,提出并推导适用于ZY-3遥感影像的LBV变换公式,探讨该方法在提高国产ZY-3卫星影像质量的可行性。首先,针对ZY-3遥感影像特点,选择9类典型地物光谱信息,通过回归分析求解回归系数;然后,根据影像典型地物空间(裸地、水体、植被)、色彩空间(红、绿、蓝)及LBV变量空间(地物总体辐射水平、可见光—近红外辐射平衡、辐射变换矢量)之间特点计算推导ZY-3卫星影像的L,B,V这3个分量;最后,利用福建省宁德市ZY-3遥感影像进行实验,定量分析评价实验结果。结果表明:①从目视效果看,相比原始影像,变换后影像更加清晰,层次感更强,细节信息也更为丰富,从而更有利于后续地物的判定、识别;②该方法得到的影像信息熵为6.21,平均梯度为4.71,偏差系数为0.46,变换后遥感影像质量较好;③该方法对ZY-3遥感影像分类的总体精度最高达89.71%,Kappa系数最高为0.875 3,分类精度较高。因此,该方法能很好地提高ZY-3遥感影像质量,可用于ZY-3遥感影像处理及后续信息提取工作。
