ABSTRACT Illegal land occupation is a pervasive challenge in South Africa, particularly urban landscapes such as Cape Town. Despite numerous studies investigating its causes, spatial distribution, and impacts, there scarcity of research focused on predicting occurrence. This study addresses this gap by developing machine learning model to identify areas susceptible illegal invasion within the Town Metropole. A random forest (RF) regression was built utilizing samples prevalence pseudoabsence. total 1070 were collected (535 points per class), with 70% used for training 30% validation. The RF demonstrated accurate predictive performance an R 2 0.809. study's findings indicate that bordering existing informal settlements are most at risk future occupation. developed can be valuable tool planners policymakers more effective strategies prevent manage

Under the framework of Rural Revitalization Strategy, optimizing layout rural settlements in mountainous areas and guiding their sustainable development must be based on a deep understanding evolution characteristics suitability evaluations. This study focuses Lixian County, located southwestern part China, Sichuan Province, as research area employs methods such average nearest neighbor index, kernel density analysis, landscape pattern index to analyze spatiotemporal 2000, 2010, 2020. Additionally, Maxent model, ecological niche theory, is applied evaluate settlements. The results reveal following: (1) County exhibit spatial distribution characterized by “sparser west, denser east, belt-like pattern”, with clustered trend. number settlement patches increased, becoming more centralized, shapes complex, connectivity between improving. (2) highly suitable land for has decreased annually, over 85% classified unsuitable layout. Suitability transitions mostly occur adjacent levels, it difficult become suitable. (3) In earlier years, was significantly influenced distance cultivated land, slope, geological hazard sites. By 2020, however, roads had second most important environmental factor, following land. Natural factors, particularly topographic features elevation were found exert greater influence than socioeconomic factors evaluating County. These findings provide scientific foundation layouts regions, offering valuable insights into transformation not only upper Minjiang River but also reference other similar regions.

Conservation areas are essential for preserving green spaces and biological diversity. Although previous studies have demonstrated that spatial optimization techniques effective balancing the relationship between ecological importance pattern during conservation practices, design of corridors still requires an efficient, intelligent, flexible workflow. In addition, functional connectivity information is usually unavailable or very difficult to obtain. To alleviate these problems, this paper has developed a new optimization-based model combines morphological analysis (MSPA) with assessment. The consideration MSPA can guarantee enough in plan, while regions higher be discovered through This method been applied planning highly city. Several experiments indicated our proposed could achieve much better performance than conventional models terms pattern. Therefore, expected assist decision processes regulation fragmented urban ecosystems.

Research on the climatic adaptation of apricot kernels (Prunus armeniaca L.) has significant meaning for optimizing their cultivation and utilizing resources effectively. This research utilizes geographical distribution data, environmental factors, soil altitude data kernel in China. By employing maximum entropy model (MaxEnt) geographic information system (ArcGIS), we identify key factors influencing China suitable areas cultivation. Our findings reveal that annual precipitation, frequency frost days April, altitude, pH, effective water content are primary impacting We classify planting suitability zones into four categories. The characterized by precipitation ranging from 330.54 mm to 616.42 mm, day 2.68 19.15 between 84.22 m 831.81 m, pH values 7.5 8.6, 1.16 3.88 deemed most growing kernels. correspond main reality.

Ecosystem cultural services (CESs) are crucial for rural revitalization and sustainable development. As research on monitoring mapping CESs continues to increase, there is a relative lack of perspectives that effectively combine spatial modeling techniques with the local context in areas. Rural areas China face challenges such as encroachment ecological service spaces displacement relocation their own characteristics during urbanization process. It enhance our understanding relationship between CES characterization locality. This paper established framework quantitative optimization We selected Ecological Green Integrated Development Demonstration Zone (EGIDZ) Yangtze River Delta subject, considering its representativeness Jiangnan Water Network Area integrated development across regions. The Maxent model was utilized integrate environmental variables locations services, facilitating evaluation CESs, well determining influence each variable. Additionally, K-means clustering employed analyze combination patterns. results indicated significant variations mean values distribution within category. natural environment, distance, human activities factors all exhibited effects shaping CESs. Furthermore, clusters were classified into three categories: CES-developed cluster, CES-developing CES-potential accounting 9.34%, 49.23%, 41.44%, respectively.

Palmer Amaranth (Amaranthus palmeri, Amaranthaceae) is one of the most competitive, troublesome, and noxious weeds causing significant yield reductions in various crops. A. palmeri was also a herbicide-resistant weed serious eco-environmental problem. Given that process invasion dynamic, plamer may already be quite severe where invasive species management surveys are chronically lacking. Predicting potential habitat can help to develop effective measures for early warning long-term detection. However, history distribution patterns China remain largely unknown.
