Land use and land cover change is driven by multiple influential factors from environmental and social dimensions in a land system. Land use practices of human decision-makers modify the landscape of the land system, possibly leading to landscape fragmentation, biodiversity loss, or environmental pollution-severe environmental or ecological impacts. While landscape-level ecological risk assessm...

Landscape Ecology is a new field of the macro-ecological research. Study on the Landscape pattern change is a research hotspot of the landscape ecology at present. The main research methods in this paper are stated as follow: using remote sensing data to get the basic landscape pattern data of Jinta Oasis in 1990 and 2000; calculating four landscape indexes by utilizing the statistics function ...

Both conservation biology and landscape planning are fields enriched by their solid grounding in professional practice and the real world. Practicing conservation biologists know that landscape planning processes affect biodiversity on the ground, and practicing landscape planners know that biodiversity issues can decisively influence acceptance of planned change. Such pragmatic recognition, ho...

Land cover change associated to urbanization processes represents one of the most insidious forms of ecosystem alteration and links frequently to other types of environmental degradation. Timely and accurate remotely sensed detection of land cover change is therefore an essential requirement for a better understanding of coupled natural and human systems in urban expansion areas. Landscape dyna...

Determination of landscape evolution is useful to well understand the physical environment and it also enables us to conduct the soil related studies. The objective of this study was to establish the historic evolution of Zayandeh-rud Valley from late Tertiary to Quaternary. To achieve this objective, the spatial structure of a representative area of Zayandeh-rud Valley in three dimensions was ...

As special depositional environments which are adjacent to the seas, deltas have provided a field for human habitat establishment. Geomorphic features of deltas are in constant transformation due to their dynamic features. Constructing dams on rivers can intensify these changes and cause either negative or positive consequences. Minab delta in Hormozgan Province of Iran is a round or crescent-s...
