Design of Rural Human Settlement Unit with the Integration of Production-Living-Ecology of China Based on Dynamic Emergy Analysis

It is of great theoretical and practical significance to optimize improve the design rural human settlement units through system ecology analysis based on emergy evaluation indices. From perspective ecology, living environment multivariate complicated, with strong correlations obscure boundaries between levels. Therefore, definition a unit in China proposed this research can be divided into three scales: microcosmic scale, mesoscale, macroscopic scale. This adopted new method for by adopting as common dimension order solve problem dimensionality disunity resource elements society economy elements. Through establishment static model dynamic prediction model, qualitative quantitative approaches were combined. According orientations industry-invigorative, environment-friendly, ecology-balanced, corresponding production-living-ecology integration, indices including self-sufficiency ratio, investment net yield environmental load sustainable calculated predicted means dynamics simulation. The results showed that ratio basically presented decreasing tendency, from 0.34 0.15 0.76 0.57, respectively, passage time; values an increasing 2.13 2.78, 1.66 2.12, 2.23 3.61, time. In practice, technical strategies spatial arrangements provide data support designing standards, planning guidelines, creating constructional instructions China.
