Explanatory Variables

The construction of the ecological environment in rural settlements is a very important part of the development of human settlements. Key to this construction is the coordinated and sustainable development of plant environment, geographical environment, and human activities. Therefore, it is necessary to study the characteristics of plant diversity and their driving mechanisms. The study area, ‘Shanchuan Town’, is located in the hilly area of Southeast China, Anji County, Zhejiang Province. As bamboo forests cover 62% of the total forests, it has the reputation of being the “China town of bamboo”. To interpret rural plant community features, we extracted topography data by the field survey, satellite image, and Digital Elevation Model (DEM) based on ArcGIS platform, then used Spearman’s correlation and a redundancy analysis to examine the relationships between explanatory variables (e.g., plot elevation, slope aspect and architectural height, etc.) and the distribution of plant community diversity. In this study, 227 plots were selected from 14 settlements to investigate totally 105, 88, 206, and 17 species of trees, shrubs, herbs, and vines, respectively, belonging to 147 families, 324 genera, and 416 species. Among them, there were 19 bamboo species, and 47 species of alien plants, which accounted for 11.3% of the total. The dominant trees and shrubs were mainly native species with high edible or ornamental value. The dominant bamboo species were common species for bamboo shoots in Zhejiang Province, while most of the dominant herbaceous species were alien species. Among the explanatory variables, the impact of plot elevation (PE) on plant community was significantly higher than those of other explanatory factors. The correlation analysis showed that the richness and diversity indices of different plant life layers were significantly related to PE. Among the architectural factors, the architectural orientation (AO) and layout type (AT) effect on shrubs and other herbaceous species was stronger than those on trees and bamboo. There was a high plant community richness in the study area, and both topography and architectural factors had a significant effect on plant community. Therefore, construction of the plant landscape should conform to the topography and regulate the residential construction activities properly, so as to get rid of urban planning thinking and the excessive pursuit of plant diversity, realizing the sustainable development of ecological environment in settlements.

Rural settlements occupy a significant part of the territory of Russia, where about 25% of the population lives and significant natural resource potential is concentrated, but the level of their socio-economic development is significantly inferior to urban ones. Increasing depressiveness of rural areas and spatial socio-economic differentiation is a systemic problem and an obstacle to the balanced development of the national economy, reduces its competitiveness due to insufficient use of economic potential, creates challenges to the economic and national security of the state. A powerful tool for countering such trends is the formation and implementation of the potential for the development of small agribusiness, which is mainly based on households created in the form of peasant (farmer) and personal subsidiary associations. The article ana-lyzes the potential of small agribusiness development in rural areas.

The landscape industry has become one of the industries with higher resource and energy consumption, and the implementation of urban low-carbon landscape construction is of great significance to improve the ecological environment. In this study, the method of low-carbon landscape construction was studied from two aspects including the carbon source control and carbon sink, as well as both direct and indirect effect. The results showed that the low-carbon landscape construction can be controlled from five aspects including landscape planning, landscape design, low-carbon landscape technology, low-carbon landscape behavior and low-carbon policy. Through a series of low-carbon measures, carbon emissions can be controlled at a reasonable level during the urban landscape construction, which also promotes the sustainable development of urban ecological environment.

Climate strongly shapes plant diversity over large spatial scales, with relatively warm and wet (benign, productive) regions supporting greater numbers of species. Unresolved aspects of this relationship include what causes it, whether it permeates to community diversity at smaller spatial scales, whether it is accompanied by patterns in functional and phylogenetic diversity as some hypotheses predict, and whether it is paralleled by climate-driven changes in diversity over time. Here, studies of Californian plants are reviewed and new analyses are conducted to synthesize climate–diversity relationships in space and time. Across spatial scales and organizational levels, plant diversity is maximized in more productive (wetter) climates, and these consistent spatial relationships are mirrored in losses of taxonomic, functional, and phylogenetic diversity over time during a recent climatic drying trend. These results support the tolerance and climatic niche conservatism hypotheses for climate–diversity relationships, and suggest there is some predictability to future changes in diversity in water-limited climates.

Indicator Analysis

The aim of the article is to present the regional differentiation of indicators characterizing the economic development of Polish regions in the context of the progress made in the implementation of the concept of sustainable development in 2010 and 2017. The authors focused primarily on determining the position of Lubuskie Province on the economic map of Poland. The article proposes a set of indicators monitoring one of the areas of sustainable development - economic development, which also take into account other areas of sustainable development, i.e. social development, environmental development, and institutional-political development. The main criterion for the selection of indicators were substantive premises and their completeness and accessibility across the regions. The analysis and evaluation of the proposed indicators (explanatory variables) were conducted within five thematic areas which mark the economic development of the regions and which are important from the standpoint of the sustainable development concept: 1) Potential of the economy 2) Innovativeness of the economy 3) Economic activity of enterprises, 4) Production and transportation, 5) Economic activity of households. The article consists of two sections. In the first section, based on literature review, the most important issues regarding the concept of sustainable development and the state of scientific research on the indicators of sustainable development at regional level are presented. The second section addresses the concept of indicator analysis on the basis of which an assessment of economic development of 16 Polish regions was carried out and the position of Lubuskie Province was determined against the backdrop of the other regions. The findings prompted an answer to the question concerning the economic development of Polish regions, and in particular of Lubuskie Province, in the context of the concept of sustainable development.Keywords: indicator analysis, region, sustainable development, economic development, Poland

Negative Density Dependence

AbstractOne of the central goals of ecology is to determine the mechanisms that enable coexistence among species. Evidence is accruing that conspecific negative density dependence (CNDD), the process by which plant seedlings are unable to survive in the area surrounding adults of their same species, is a major contributor to tree species coexistence. However, for CNDD to maintain diversity, three conditions must be met. First, CNDD must maintain diversity for the majority of the woody plant community (rather than merely specific groups). Second, the pattern of repelled recruitment must increase in with plant size. Third, CNDD must occurs across life history strategies and not be restricted to a single life history strategy. These three conditions are rarely tested simultaneously. In this study, we simultaneously test all three conditions in a woody plant community in a North American temperate forest. We examined whether the different woody plant growth forms (shrubs, understory trees, mid-story trees, canopy trees, and lianas) at different ontogenetic stages (seedling, sapling, and adult) were overdispersed – a spatial pattern indicative of CNDD – using spatial point pattern analysis across life history stages and strategies. We found that there was a strong signal of overdispersal at the community level. However, this pattern was driven by adult canopy trees. By contrast, understory plants, which can constitute up to 80% of temperate forest plant diversity, were not overdispersed as adults. The lack of overdispersal suggests that CNDD is unlikely to be a major mechanism maintaining understory plant diversity. The focus on trees for the vast majority of CNDD studies may have biased the perception of the prevalence of CNDD as a dominant mechanism that maintains community-level diversity when, according to our data, CNDD may be restricted largely to trees.
