Heterogeneous network-based land pattern succession simulation system

Abstract

The invention provides a heterogeneous network-based land pattern succession simulation system. The system comprises a PDA client and a server terminal, wherein the PDA client is used for transmitting a sampling parameter and a user set parameter to the server terminal in response to a user command, and receiving a simulated calculation result from the server terminal; and the server terminal is used for responding to the PDA client, automatically extracting stored basic data related to the sampling parameter and the user set parameter, performing an simulation operation on the related basic data by using a land use pattern succession simulation module, and acquiring a simulated calculation result corresponding to a specified simulation time period. On the basis of an independently researched and developed land use pattern succession simulation model, the system carries out real-time parallel computing on a data-shared mechanism by taking a high-performance computer workstation as a service platform, thereby providing a simple, convenient and fast, intelligent and quantitative land use pattern succession simulation terminal for a land use planner.

Description

technical field [0001] The invention relates to the technical field of resource development and utilization, in particular to a land use pattern change simulation system for land resource development and land planning. Background technique [0002] Land use reflects the existence of all natural factors such as topography, landform, soil, basic geology, hydrology, climate and vegetation in a certain area, as well as past and current human activities on land resource development and utilization in this area. affect the result. [0003] The succession simulation of land use pattern aims to answer when, where, why and how the land use structure changes and transforms, and what kind of prominent environmental effects it leads to. The development and application of the land use pattern succession simulation system can deepen people's understanding of the dynamic change mechanism of the land use system, and provide an analysis tool for predicting the future dynamic change trend of...

AI Technical Summary

Problems solved by technology

[0004] The traditional land use planning method is greatly affected by human subjective factors, cannot dynamically reflect the whole process of land use planning layout, and is difficult to meet the needs of intelligent processing of land planning information

[0005] At present, most of the models and methods that can carry out the simulation of land use pattern succession often only involve one or several types of land use, lack an overall grasp of the regional land use pattern succession pattern, and are rarely able to quantify the succession pattern from the fine grid level. Analysis of the driving effects of natural, ecological, and socio-economic factors, lack of proper regional land use structure scenario analysis and in-depth analysis of land use change pre
