Sustainable ecological and environmental development is the basis of regional development. The sensitivity classification of the ecological environment is the premise of its spatial distribution for land use planning. In this paper, a fuzzy matter-element model and factor-overlay method were employed to analyze the ecological sensitivity in Yicheng City. Four ecological indicators, including so...

A theory of geometric continuity of arbitrary order is presented. Conditions of geometric continuity at a vertex where a number of patches meet are investigated. Geometric continuous patch complexes are introduced as the appropriate setting for the representation of surfaces in CAGD. The theory is applied to the modelling of closed surfaces and the fitting of triangular patches into a geometric...

land-use planning is a science that determines the type optimum of land-use through studying the ecological characteristics of the land as well as its socio-economic structure. the primary objective of this study is to evaluate the land-use and natural resources for future sustainable land planning using gis. in this study, the makhdoom’s systematic method was used to analyze the ecological and...

In the socioecological landscape planning of natural resources, as presented in this article, sociocultural and ecological decision criteria are considered with ‘traditional’ timber production analyses in an integrated and holistic way. As the main phases, the approach involves: pinpointing sites that are important with respect to management objectives related to ecological or sociocultural con...

The need for social-ecological systems to become more adaptive is widely acknowledged. Social effects generated by participatory planning have been claimed to contribute to this transformation, but little empirical evidence is available that backs up or opposes this notion. We aimed to offer some insights regarding questions as to which social effects are formed in participatory planning proces...
