“…The values for the physiographic compartmentalization were established according to the different vulnerabilities and characteristics of each unit and its potential to geological processes, such as mass movements, linear erosion and floods, associated with the respective slope values found in each one, as well as indications of the surface dynamics processes identified in the aerial image analysis and field investigations. In this context, several authors, such as Feizizadeh and Blaschke (2013), Elsheikh et al (2015), Kong et al (2016) and Ross (2006) have been using physiographic criteria and presence of surface dynamics processes as hierarchical parameters to obtain maps of environmental susceptibility and geo-environmental zoning, in which the method to overlay variables, such as slope, altimetry and geological units and geomorphological data, are selected as indicators for obtaining homogeneous units that synthesize their main potentialities and implications.…”

The geo-environmental zoning represents an important strategy in the territorial management. However, it requires a logical and structured procedure. Therefore, an approach using physiographic compartmentalization is proposed and applied as case study in a region covered by the topographic maps of São José dos Campos and Jacareí, Brazil. This region has great geological and geomorphological peculiarities, beyond being a place with large human interventions because of its quickly economic growth. The methodology is based on photointerpretation techniques and remote sensing in GIS environment. As a result, seven geo-environmental zones were obtained from a weighted integration by multicriteria analysis of physiographic units with land-use classes. In conclusion, taking into account potentialities and limitations, the proposed approach can be considered able to support sustainable decision-making, being applicable in other regions.

“…Scientists have done many studies on evaluating land suitability; in the 1960s, land suitability evaluation was the main basis for urban planning [29], and since the 1970s GIS techniques have encouraged the development of land suitability evaluation [24,25,[30][31][32][33][34][35]. Catching up with new advances in the technologies of data collection and processing, the land suitability technique is applied in various fields including crop suitability evaluation [36][37][38][39][40], landscape planning and hazards [41,42], water management and planning [43][44][45], evaluation of the environmental impacts [46,47], evaluation of land uses [48][49][50], and sustainable urban development [51][52][53][54].…”

The management of land use in big cities and capitals and the surrounding adjacent urban aggregates is still of major importance in the field of urban development, especially in cities with populations of millions and various types of land uses and economic activities. The rural–urban continuum between the cities of Ar Riyadh and Al Kharj suffers from an unclear general land use trend, due to urban expansion at the expense of the agriculture lands, the imbalance of the population compound, the deterioration of the urban fabric, lack and poor distribution of services, and the dominance of industrial land use at the expense of other uses. These factors have led to an increase in environmental changes and loss of the environmental and ecological characteristics of this area between Ar Riyadh and Al Kharj. The present study aims at evaluating the land use suitability for urban development in the rural–urban continuum between Ar Riyadh and Al Kharj cities. This is achieved by using the GIS-based Multi Criteria decision Analysis (GIS-MCDA) on twelve various economic, environmental, urban, and law criteria. The weights of criteria were determined using the Analytic Hierarchy Process (AHP) method. The results of the spatial suitability map of the land use for sustainable urban development revealed that there are five categories of spatial suitability ranging in suitability from 32% to 86%. The recommended areas for sustainable urban development are those with a spatial suitability upwards of 70% in the rural–urban continuum corridor between Ar Riyadh and Al Kharj cities. The sustainable development in this corridor can be achieved by executing high priority projects that ensure and support the urban sustainable development plan through establishing four local urban development centers and upgrading four current villages to rural communities, aiming at strengthening the functional bonds between the rural communities and the local urban development centers. These projects will limit the sustainable urban development to specific areas without allowing random expansion, avoiding the urban conjugation of the two Ar Riyadh and Al Kharj cities through the connecting area between them.

“…In 2015, Jiang X et al proposed a common comprehensive index method and a new support vector machine (SVM) model, and compared them to evaluate the geological environment quality of mining [2]. Kong C et al presented an integrated technique using back-propagation neural network (BPNN) and geographic information system (GIS) to assess suitability for agricultural land based on geo-environmental factors in the rural-urban fringe [3]; Chen X et al used the weights-of-evidence method based on ArcGIS to evaluate the sensitivity of debris flow in Kangding County [4]. In 2017, Du Qian et al used a combination of Logistic regression and information model to evaluate the landslide susceptibility [5].…”

The Shiyan-Wudang Mountain area is located in the Danjiangkou Reservoir Area, the upper reaches of the Han River, the hinterland of the Qinba Mountain Range. The main geological environmental problems in the region include collapse, landslides, debris flow, ground collapses, and ground fissures, which seriously restrict local economic development. Based on the analysis and summary of the distribution, development characteristics, formation conditions and influencing factors of geological disasters in this area, the multiple comparisons is used to select the formation complex, slope, distance from the fault zone, water yield property, distance from surface water system, average annual rainfall, mountain disaster point density, soil erosion, and human engineering activity intensity as the evaluation indicators, the geological environment quality evaluation index system of Shiyan-Wudang Mountain area was established; Geographic information system (GIS) technology is used to carry out hierarchical management of basic maps, and establish a spatial database of geological environment conditions. The analytic hierarchy process is used to determine the weight of the index system. The evaluation module developed by MapGIS platform is used to evaluate the geological environment quality of the study area. Respectively, the area of geological environment with best quality, good, poor and worst areas accounted for 56.805%, 22.800%, 16.474%, and 3.921%. The results show that the geological environment quality of the study area is generally good, and some areas are poor, and very few are bad. The calculated evaluation map is compared with the current geological disaster points, and the results verify the accuracy and scientificity of the evaluation process and results. The research results of this paper can provide a basis for regional geological environment management, planning, disaster prevention and mitigation.
