Analysis of the landscape spatial pattern influence caused by land development and consolidation

Forecasting the landscape spatial pattern influence quantitively caused by land development and consolidation planning is an important part of environment impact assessment before the planning is brought into effect. Area-weighted mean shape index, mean euclidean nearest neighbor distance, etc. were identified to analyze quantitatively the landscape spatial pattern and influence on class-level. The landscape spatial pattern and influence on landscape-level were expressed by dominance index, contagion index, cohesion index, etc. Applying those landscape ecology indexes landscape spatial pattern influence caused by the land development and consolidation planning of Yanqing county, Beijing city was studied by comparing landscape characteristics between those before and after planning implementation. The results showed that each index had changed dramatically.
