熵视角下的重庆市乡村生产空间系统状态量化研究

在一定时空特征下,乡村生产空间系统状态是乡村生产空间系统的即时表现,既是乡村生产空间系统演化的结果,也是乡村生产空间系统演化的前提.以重庆市为研究区,从乡村生产活动无序度和乡村生产空间承载力2个维度构建乡村生产空间系统状态量化指标体系,进而建立乡村生产空间系统熵模型测度系统熵值,探析重庆市乡村生产空间系统状态,并将该系统状态划分为3种类型.研究表明:重庆市乡村生产空间系统熵值为-0.431,乡村生产空间系统总体处于稳定状态,表现为各区(县)乡村生产空间系统状态的叠加;各区(县)乡村生产空间系统状态的稳定性在空间上以"T"字型为中心向四周递增,系统状态类型主要分为冲突矛盾型、临界警戒型与和谐共融型3种类型.

Quantitative Research on the State of Rural Production Space System of Chongqing in the Perspective of Entropy

In a circumstance of certain spatial and temporal characteristics, the state of the rural production space system is the immediate manifestation of the rural production space system, which is not only the result but also the premise of the evolution of the rural production space system. This article takes Chongqing Municipality as the study area, establishes a quantitative index system of the rural production space system from two dimensions:the disorder degree of rural production activities and the carrying capacity of rural production space, and builds a rural production space system entropy model to measure the entropy value of the rural production space system. Then, on this basis, the status of the rural production space system in Chongqing Municipality is analyzed and its types classified. The study shows that the system entropy of rural production space system of Chongqing Municipality is minus 0.431, which is generally in a stable state, and is shown as a superposition of the state of rural production space system of each county. The stability of the state of rural production space system of the 37 counties manifests a T-shaped spatial distribution, with a progressive increase from the center to the periphery, which consists of 3 types of the state of rural production space system:the conflict type, the critical type and the harmony type.
