TL;DR: Assessment of water quality according to the biological indicators of phytoplankton revealed that the quality was of middle-poor trophic type; however, according to nutrient indicators, the coastal area of Leizhou Peninsula was designated as nitrogen- limited mesotrophic or nitrogen-limited potential eutrophication.

TL;DR: In this paper, the influence of offshore wave energy generators on marine macro-faunal communities, interactions between offshore WEGs and biofouling organisms, impacts of offshore wEGs on marine birds and of electromagnetic fields (EMFs) on marine animals as well as "artificial reef" effects.

TL;DR: The results indicated that parasitism of C.australis could inhibit the growth of A.philoxeroides and increase community diversity,facilitating the restoration of native communities.

TL;DR: In this paper, the authors investigated the distribution of POC and its sources in the Pearl River Estuary in summer through the POC measurements of 20 sites in August 2010, and the results showed that the concentrations in the bottom waters layers were higher than those in the surface water layers.

TL;DR: In this article, the water use efficiency of intercropping walnut, monoculture wheat and inter-cropping wheat in a low hilly area of North China was investigated.

TL;DR: The Shahaoqu irrigation district was chosen as an example for testing the spatial variability of soil salinity and its relationship to depth to groundwater and the results showed that the soil EC′s Cv values were more than 36% in Shahao irrigation area and had strong spatial variability in different irrigation periods and different soil depths.

TL;DR: Based on SPOT-VGT 10-day composite data over the Circum Bohai Bay Region from 1999 to 2009, the authors performs the Mann-Kendall test and calculates the trend Slope ( β ) and Hurst index of time series data to study the temporal trends and long-range dependence of Normalized Difference Vegetation Index (NDVI) on 1-km spatial scale, and plots monthly calendar and seasonal succession map using spatial analysis techniques, and then analyze and reveal the spatial-temporal characteristics of vegetation coverage.

TL;DR: Fine root survivorship was monitored by minirhizotrons during two successive years in two subtropical evergreen broadleaved forests in Wanmulin Natural Reserve,Jian-ou,Fujian province and showed that in both two forests year of birth had no significant effects on root longevity.

TL;DR: In this article, the influence of vegetation on permafrost was systematically reviewed, and some problems unresolved in the research at present are identified in this paper, and the prospect for further study is also proposed.

TL;DR: This work critically evaluated the control methods and strategies that have been developed and adopted in the past ten years to provide scientific evidences for controlling the invasive plant.

TL;DR: Sonneratia apetala grows well in intertidal zones of thick and soft muddy soil with low salinity in China′s south coasts, and can be used as pioneer species in mangrove afforestation due to its fast-growth, high adaptability and stress resistance, but will threaten the growth of indigenous mangroves species if it is introduced to nativeMangrove communities or planted densely with indigenous species.

TL;DR: Results indicated that airborne pollen composition was consistent with the vegetation components and the pollination periods of the plants in the sampling site, and the variations of pollen numbers were affected positively by temperature, negatively by relative humidity and precipitation.

TL;DR: The concept of agroecosystem health plays an important conceptual role in evaluating agro-eco-systems and agricultural research as discussed by the authors, and the development of Agro-ECoSystem health research is reviewed, and agroECosystemhealth from various dimensions is provided.

TL;DR: Wang et al. as discussed by the authors compared soil nutrient status, microbial biomass nitrogen and enzyme activities under five different land use patterns (nature forest, park, farmland, street green, and roadside tree sites at various soil depths in Beijing, China).

TL;DR: In this paper, a review of the landscape pattern analysis for urban heat island mitigation is presented, and the future trends on landscape pattern are finally proposed: (1) to collect or derive appropriate data based on the purpose of the study; (2) to conduct more landscape pattern simulation research rather than statistics, and furthermore to simulate 2D(Dimensional) and 3D and to construct 2/3D landscape indexes in UHI simulation models; (3) to use more multi-spectral and the thermal remote sensing data, and in-situ or simulated data as

TL;DR: In this article, the ameliorating effect of planting alfalfa (Medicago sativa) on salt-affected soils was assessed in field experiments in the irrigated region of Qingwangchuan basin for 5 years.

TL;DR: This review on key ecological research status and prospects on invasive Liriomyza spp.

TL;DR: Wang et al. as discussed by the authors reviewed the recent advances in wetlands degradation research in nine areas: wetland degradation standards, degradation characteristics, classification of degradation, degradation process and mechanism, index system for degradation monitoring,index system for degrading assessment, new technology for degrading monitoring, ecological restoration theory and technology of degraded wetlands.

TL;DR: In this article, the authors summarized the eco-efficiency counting methods and applications in different scales have been sum up based on the review of relevant literature in recent ten years and divided them into three categories: economic/environmental single ratio method, indicator system method and data envelopment analysis method.

TL;DR: The results showed that H. rhamnoides could form strong symbiotic relationships with AM fungi, and there existed obvious differences in AM fungal colonization among five sampling sites in the Loess Plateau.

TL;DR: In this article, the authors analyzed the spatial expansion characteristics of urban land in the three agglomerations and compared them to the level of socio-economic development (population urbanization rate and the proportion of secondary and tertiary industry in GDP).

TL;DR: The endangered plant T.mongolica is less able to maintain turgor pressure and has a lower water potential, which gives it a lower level of drought resistance than Z.xanthoxylon, and this demonstrates its weaker photosynthetic capability and lower adaptability to a drought prone environment.
