Modeling the Impacts of Urbanization on Regional Climate Change: A Case Study in the Beijing-Tianjin-Tangshan Metropolitan Area

Table 3

Land use changes in Beijing-Tianjin-Tangshan Metropolitan area, 1995–2005.

Year/period	Cultivated land (%)	Forestry area (%)	Grassland (%)	Water area (%)	Built-up area (%)	Unused land (%)
1995	48.48%	24.59%	6.32%	5.54%	14.14%	0.92%
2005	47.50%	22.45%	6.74%	5.08%	17.48%	0.76%
Change 2005–1996∗	−0.10%	−0.21%	0.04%	−0.05%	0.33%	−0.02%

Note: ∗represents the change rate calculated with the following equation: (𝐴_𝑖²⁰⁰⁵−𝐴_𝑖¹⁹⁹⁵)/(10), where 𝐴_𝑖²⁰⁰⁵ means the area proportion of land use type 𝑖 in 2005 and 𝐴_𝑖¹⁹⁹⁵ means the area proportion of land use type 𝑖 in 1995.
