In this study, the definition and connotation of the ecological water storage of marsh is discussed, and its distinction and relationship with ecological water requirement are also analyzed. Furthermore, the gist and method of calculating ecological
water storage and ecological water requirement have been provided, and Momoge wetland, (located in Zhenlai county, Jilin Province, China), has been given as an example of calculation of the two variables. Ecological water use of marsh can be ascertained
according to ecological water storage and ecological water requirement.
Following the previous report on this subject, published in 2007, there has been a very substantial increase in publications relevant to landscape ecology. The continuing identity crisis of landscape ecology is described and recent literature
in the field is then summarized under the following headings : Landscape ecology and climate research; Alternatives to fragmentation and the patch-based model - the links between pattern and process; Fragmentation research; Methodology and techniques
in landscape ecology; and Connectivity and graph theoretical approaches. The review concludes that landscape ecology now represents one important focus within biogeography, linked to ecological biogeography, and takes its place alongside other key foci

Studying the change of resources consumption and eco-environmental carrying capacity are of importance to the sustainable development of urbanization. Based on the China's economic and social statistical data from 1950 to 2006, the ecological
footprint, ecological footprint intensity, ecological deficit and surplus, and eco-environment quality comprehensive index are calculated, the correlation between urbanization and eco-environmental change is analyzed and the eco-environmental guarantee
This paper highlights some of the new research fields in landscape ecology, which has developed rapidly over the last 2 decades. The AA. also analyse the development of some classical branches of landscape ecology regarding pattern and process

This paper evaluates the recent use of remote sensing in landscape ecology. First, to provide an overview of current practice, 438 research papers published in the journal Landscape Ecology for the years 2004—2008 were examined for information about
use of remote sensing. Selected case studies are then presented that illustrate the potential value of using diverse remote sensing data together with ecological field data, as an integrated approach to landscape ecology research. Finally, the future
development of landscape ecology as a predictive scientific discipline is considered, with particular reference to the potential role of remote sensing.

through visually interpreted Landsat TM images of 1989, 1996 and 2005. It is believed that there were a series of landscape ecological problems caused by city expansion. For this reason, this study adopted accumulative cost distance model, combined
with ecosystem services and spatial interactions of landscape types, analyzed the spatial difference of the ecological function and the compactness of landscape structure in the study area, and further discussed the landscape pattern optimization proposal
. Results are presented in the context of landscape ecological planning in Beijing region : to establish urban ecological corridors and pattern in the course of city expansion.

of national and subnational ‘ecological footprints’. They generated a global constructed area density grid for the 2000—2001 period using satellite observed nighttime lights and a population count grid from the US Department of Energy. Satellite data inputs
area per person index can serve as a proxy measure of ecological footprints at both the national and subnational level. This relatively simple and globally uniform measure of human impact on the environment correlates strongly with other more difficult

Observations and measurements were made of physical and ecological changes that have occurred since 1985 at a tundra site near Healy, Alaska. Air temperatures decreased (1985 through 1999) while permafrost warmed and thawed creating thermokarst
