Các đặc điểm phân bố không gian của chỉ số rủi ro hạn hán toàn diện ở khu vực tây nam Trung Quốc và nguyên nhân tiềm ẩn
Tóm tắt
Hạn hán là một vấn đề nghiêm trọng ở tây nam Trung Quốc, nơi mà rủi ro hạn hán vượt quá mức trung bình toàn quốc. Biến đổi khí hậu có khả năng làm trầm trọng thêm vấn đề này, qua đó đe dọa an ninh lương thực của Trung Quốc. Trong bài báo này, chúng tôi đã sử dụng quy trình phân tích hiệnh iérarchique cùng với dữ liệu khí tượng, địa lý, đất đai và viễn thám để xây dựng một mô hình đánh giá rủi ro hạn hán dựa trên các yếu tố như mối nguy hạn hán, độ nhạy cảm và khả năng tiếp xúc của các giá trị gặp rủi ro, cũng như khả năng ngăn chặn hoặc giảm thiểu vấn đề này. Sử dụng mô hình, chúng tôi đã đánh giá rủi ro hạn hán (được định nghĩa bằng chỉ số rủi ro hạn hán toàn diện, R) và sự phân bố không gian của nó ở tây nam Trung Quốc, từ đó phát hiện mô hình phân vùng phức tạp. Phần phía đông của khu vực nghiên cứu có rủi ro cực kỳ cao, và rủi ro nói chung cao hơn ở phía bắc so với phía nam, và tăng từ tây nam đến đông bắc. Rủi ro toàn diện (R) thấp nhất ở tỉnh Vân Nam. Nó cao nhất ở tỉnh Tứ Xuyên và thành phố Trùng Khánh. Đóng góp của các yếu tố rủi ro vào R cao nhất với khả năng ngăn chặn và giảm thiểu, theo sau đó là mối nguy hạn hán, độ nhạy cảm và khả năng tiếp xúc, và độ nhạy cảm môi trường.
